+# Fetch
+
+Undici exposes a fetch() method starts the process of fetching a resource from the network.
+
+Documentation and examples can be found on [MDN](https://developer.mozilla.org/en-US/docs/Web/API/fetch).
+
+## FormData
+
+This API is implemented as per the standard, you can find documentation on [MDN](https://developer.mozilla.org/en-US/docs/Web/API/FormData).
+
+If any parameters are passed to the FormData constructor other than `undefined`, an error will be thrown. Other parameters are ignored.
+
+## Response
+
+This API is implemented as per the standard, you can find documentation on [MDN](https://developer.mozilla.org/en-US/docs/Web/API/Response)
+
+## Request
+
+This API is implemented as per the standard, you can find documentation on [MDN](https://developer.mozilla.org/en-US/docs/Web/API/Request)
+
+## Header
+
+This API is implemented as per the standard, you can find documentation on [MDN](https://developer.mozilla.org/en-US/docs/Web/API/Headers)
+
+# Body Mixins
+
+`Response` and `Request` body inherit body mixin methods. These methods include:
+
+- [`.arrayBuffer()`](https://fetch.spec.whatwg.org/#dom-body-arraybuffer)
+- [`.blob()`](https://fetch.spec.whatwg.org/#dom-body-blob)
+- [`.bytes()`](https://fetch.spec.whatwg.org/#dom-body-bytes)
+- [`.formData()`](https://fetch.spec.whatwg.org/#dom-body-formdata)
+- [`.json()`](https://fetch.spec.whatwg.org/#dom-body-json)
+- [`.text()`](https://fetch.spec.whatwg.org/#dom-body-text)
+
+There is an ongoing discussion regarding `.formData()` and its usefulness and performance in server environments. It is recommended to use a dedicated library for parsing `multipart/form-data` bodies, such as [Busboy](https://www.npmjs.com/package/busboy) or [@fastify/busboy](https://www.npmjs.com/package/@fastify/busboy).
+
+These libraries can be interfaced with fetch with the following example code:
+
+```mjs
+import { Busboy } from '@fastify/busboy'
+import { Readable } from 'node:stream'
+
+const response = await fetch('...')
+const busboy = new Busboy({
+  headers: {
+    'content-type': response.headers.get('content-type')
+  }
+})
+
+Readable.fromWeb(response.body).pipe(busboy)
+```

+# Class: MockPool
+
+Extends: `undici.Pool`
+
+A mock Pool class that implements the Pool API and is used by MockAgent to intercept real requests and return mocked responses.
+
+## `new MockPool(origin, [options])`
+
+Arguments:
+
+* **origin** `string` - It should only include the **protocol, hostname, and port**.
+* **options** `MockPoolOptions` - It extends the `Pool` options.
+
+Returns: `MockPool`
+
+### Parameter: `MockPoolOptions`
+
+Extends: `PoolOptions`
+
+* **agent** `Agent` - the agent to associate this MockPool with.
+
+### Example - Basic MockPool instantiation
+
+We can use MockAgent to instantiate a MockPool ready to be used to intercept specified requests. It will not do anything until registered as the agent to use and any mock request are registered.
+
+```js
+import { MockAgent } from 'undici'
+
+const mockAgent = new MockAgent()
+
+const mockPool = mockAgent.get('http://localhost:3000')
+```
+
+## Instance Methods
+
+### `MockPool.intercept(options)`
+
+This method defines the interception rules for matching against requests for a MockPool or MockPool. We can intercept multiple times on a single instance, but each intercept is only used once. For example if you expect to make 2 requests inside a test, you need to call `intercept()` twice. Assuming you use `disableNetConnect()` you will get `MockNotMatchedError` on the second request when you only call `intercept()` once.
+
+When defining interception rules, all the rules must pass for a request to be intercepted. If a request is not intercepted, a real request will be attempted.
+
+| Matcher type | Condition to pass          |
+|:------------:| -------------------------- |
+| `string`     | Exact match against string |
+| `RegExp`     | Regex must pass            |
+| `Function`   | Function must return true  |
+
+Arguments:
+
+* **options** `MockPoolInterceptOptions` - Interception options.
+
+Returns: `MockInterceptor` corresponding to the input options.
+
+### Parameter: `MockPoolInterceptOptions`
+
+* **path** `string | RegExp | (path: string) => boolean` - a matcher for the HTTP request path. When a `RegExp` or callback is used, it will match against the request path including all query parameters in alphabetical order. When a `string` is provided, the query parameters can be conveniently specified through the `MockPoolInterceptOptions.query` setting.
+* **method** `string | RegExp | (method: string) => boolean` - (optional) - a matcher for the HTTP request method. Defaults to `GET`.
+* **body** `string | RegExp | (body: string) => boolean` - (optional) - a matcher for the HTTP request body.
+* **headers** `Record<string, string | RegExp | (body: string) => boolean`> - (optional) - a matcher for the HTTP request headers. To be intercepted, a request must match all defined headers. Extra headers not defined here may (or may not) be included in the request and do not affect the interception in any way.
+* **query** `Record<string, any> | null` - (optional) - a matcher for the HTTP request query string params. Only applies when a `string` was provided for `MockPoolInterceptOptions.path`.
+* **ignoreTrailingSlash** `boolean` - (optional) - set to `true` if the matcher should also match by ignoring potential trailing slashes in `MockPoolInterceptOptions.path`.
+
+### Return: `MockInterceptor`
+
+We can define the behaviour of an intercepted request with the following options.
+
+* **reply** `(statusCode: number, replyData: string | Buffer | object | MockInterceptor.MockResponseDataHandler, responseOptions?: MockResponseOptions) => MockScope` - define a reply for a matching request. You can define the replyData as a callback to read incoming request data. Default for `responseOptions` is `{}`.
+* **reply** `(callback: MockInterceptor.MockReplyOptionsCallback) => MockScope` - define a reply for a matching request, allowing dynamic mocking of all reply options rather than just the data.
+* **replyWithError** `(error: Error) => MockScope` - define an error for a matching request to throw.
+* **defaultReplyHeaders** `(headers: Record<string, string>) => MockInterceptor` - define default headers to be included in subsequent replies. These are in addition to headers on a specific reply.
+* **defaultReplyTrailers** `(trailers: Record<string, string>) => MockInterceptor` - define default trailers to be included in subsequent replies. These are in addition to trailers on a specific reply.
+* **replyContentLength** `() => MockInterceptor` - define automatically calculated `content-length` headers to be included in subsequent replies.
+
+The reply data of an intercepted request may either be a string, buffer, or JavaScript object. Objects are converted to JSON while strings and buffers are sent as-is.
+
+By default, `reply` and `replyWithError` define the behaviour for the first matching request only. Subsequent requests will not be affected (this can be changed using the returned `MockScope`).
+
+### Parameter: `MockResponseOptions`
+
+* **headers** `Record<string, string>` - headers to be included on the mocked reply.
+* **trailers** `Record<string, string>` - trailers to be included on the mocked reply.
+
+### Return: `MockScope`
+
+A `MockScope` is associated with a single `MockInterceptor`. With this, we can configure the default behaviour of an intercepted reply.
+
+* **delay** `(waitInMs: number) => MockScope` - delay the associated reply by a set amount in ms.
+* **persist** `() => MockScope` - any matching request will always reply with the defined response indefinitely.
+* **times** `(repeatTimes: number) => MockScope` - any matching request will reply with the defined response a fixed amount of times. This is overridden by **persist**.
+
+#### Example - Basic Mocked Request
+
+```js
+import { MockAgent, setGlobalDispatcher, request } from 'undici'
+
+const mockAgent = new MockAgent()
+setGlobalDispatcher(mockAgent)
+
+// MockPool
+const mockPool = mockAgent.get('http://localhost:3000')
+mockPool.intercept({ path: '/foo' }).reply(200, 'foo')
+
+const {
+  statusCode,
+  body
+} = await request('http://localhost:3000/foo')
+
+console.log('response received', statusCode) // response received 200
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')) // data foo
+}
+```
+
+#### Example - Mocked request using reply data callbacks
+
+```js
+import { MockAgent, setGlobalDispatcher, request } from 'undici'

+  method: 'GET',
+  headers: {
+    'User-Agent': 'undici',
+    Host: 'example.com'
+  }
+}).reply(200, ({ headers }) => ({ message: headers.get('message') }))
+
+const { statusCode, body, headers } = await request('http://localhost:3000', {
+  headers: {
+    message: 'hello world!'
+  }
+})
+
+console.log('response received', statusCode) // response received 200
+console.log('headers', headers) // { 'content-type': 'application/json' }
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')) // { "message":"hello world!" }
+}
+```
+
+#### Example - Mocked request using reply options callback
+
+```js
+import { MockAgent, setGlobalDispatcher, request } from 'undici'
+
+const mockAgent = new MockAgent()
+setGlobalDispatcher(mockAgent)

+}).reply(({ headers }) => ({ statusCode: 200, data: { message: headers.get('message') }})))
+
+const { statusCode, body, headers } = await request('http://localhost:3000', {
+  headers: {
+    message: 'hello world!'
+  }
+})
+
+console.log('response received', statusCode) // response received 200
+console.log('headers', headers) // { 'content-type': 'application/json' }
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')) // { "message":"hello world!" }
+}
+```
+
+#### Example - Basic Mocked requests with multiple intercepts
+
+```js
+import { MockAgent, setGlobalDispatcher, request } from 'undici'
+
+const mockAgent = new MockAgent()
+setGlobalDispatcher(mockAgent)
+
+const mockPool = mockAgent.get('http://localhost:3000')

+
+const result1 = await request('http://localhost:3000/foo')
+
+console.log('response received', result1.statusCode) // response received 200
+
+for await (const data of result1.body) {

+
+for await (const data of result2.body) {
+  console.log('data', data.toString('utf8')) // data hello
+}
+```
+
+#### Example - Mocked request with query body, request headers and response headers and trailers
+
+```js
+import { MockAgent, setGlobalDispatcher, request } from 'undici'
+
+const mockAgent = new MockAgent()
+setGlobalDispatcher(mockAgent)
+
+const mockPool = mockAgent.get('http://localhost:3000')

+  console.log('data', data.toString('utf8')) // '{"foo":"bar"}'
+}
+
+console.log('trailers', trailers) // { 'content-md5': 'test' }

+# Class: ProxyAgent
+
+Extends: `undici.Dispatcher`
+
+A Proxy Agent class that implements the Agent API. It allows the connection through proxy in a simple way.
+
+## `new ProxyAgent([options])`
+
+Arguments:
+
+* **options** `ProxyAgentOptions` (required) - It extends the `Agent` options.
+
+Returns: `ProxyAgent`
+
+### Parameter: `ProxyAgentOptions`
+
+Extends: [`AgentOptions`](/docs/docs/api/Agent.md#parameter-agentoptions)
+> It ommits `AgentOptions#connect`.
+
+> **Note:** When `AgentOptions#connections` is set, and different from `0`, the non-standard [`proxy-connection` header](https://udger.com/resources/http-request-headers-detail?header=Proxy-Connection) will be set to `keep-alive` in the request.
+
+* **uri** `string | URL` (required) - The URI of the proxy server.  This can be provided as a string, as an instance of the URL class, or as an object with a `uri` property of type string.
+If the `uri` is provided as a string or `uri` is an object with an `uri` property of type string, then it will be parsed into a `URL` object according to the [WHATWG URL Specification](https://url.spec.whatwg.org).
+For detailed information on the parsing process and potential validation errors, please refer to the ["Writing" section](https://url.spec.whatwg.org/#writing) of the WHATWG URL Specification.
+* **token** `string` (optional) - It can be passed by a string of token for authentication.
+* **auth** `string` (**deprecated**) - Use token.
+* **clientFactory** `(origin: URL, opts: Object) => Dispatcher` (optional) - Default: `(origin, opts) => new Pool(origin, opts)`
+* **requestTls** `BuildOptions` (optional) - Options object passed when creating the underlying socket via the connector builder for the request. It extends from [`Client#ConnectOptions`](/docs/docs/api/Client.md#parameter-connectoptions).
+* **proxyTls** `BuildOptions` (optional) - Options object passed when creating the underlying socket via the connector builder for the proxy server. It extends from [`Client#ConnectOptions`](/docs/docs/api/Client.md#parameter-connectoptions).
+* **proxyTunnel** `boolean` (optional) - For connections involving secure protocols, Undici will always establish a tunnel via the HTTP2  CONNECT extension. If proxyTunnel is set to true, this will occur for unsecured proxy/endpoint connections as well. Currently, there is no way to facilitate HTTP1 IP tunneling as described in https://www.rfc-editor.org/rfc/rfc9484.html#name-http-11-request. If proxyTunnel is set to false (the default), ProxyAgent connections where both the Proxy and Endpoint are unsecured will issue all requests to the Proxy, and prefix the endpoint request path with the endpoint origin address.
+
+Examples:
+
+```js
+import { ProxyAgent } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+// or
+const proxyAgent = new ProxyAgent(new URL('my.proxy.server'))
+// or
+const proxyAgent = new ProxyAgent({ uri: 'my.proxy.server' })
+// or
+const proxyAgent = new ProxyAgent({
+  uri: new URL('my.proxy.server'),
+  proxyTls: {
+    signal: AbortSignal.timeout(1000)
+  }
+})
+```
+
+#### Example - Basic ProxyAgent instantiation
+
+This will instantiate the ProxyAgent. It will not do anything until registered as the agent to use with requests.
+
+```js
+import { ProxyAgent } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+```
+
+#### Example - Basic Proxy Request with global agent dispatcher
+
+```js
+import { setGlobalDispatcher, request, ProxyAgent } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+setGlobalDispatcher(proxyAgent)
+
+const { statusCode, body } = await request('http://localhost:3000/foo')
+
+console.log('response received', statusCode) // response received 200
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')) // data foo
+}
+```
+
+#### Example - Basic Proxy Request with local agent dispatcher
+
+```js
+import { ProxyAgent, request } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+
+const {
+  statusCode,
+  body
+} = await request('http://localhost:3000/foo', { dispatcher: proxyAgent })
+
+console.log('response received', statusCode) // response received 200
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')) // data foo
+}
+```
+
+#### Example - Basic Proxy Request with authentication
+
+```js
+import { setGlobalDispatcher, request, ProxyAgent } from 'undici';
+
+const proxyAgent = new ProxyAgent({
+  uri: 'my.proxy.server',
+  // token: 'Bearer xxxx'
+  token: `Basic ${Buffer.from('username:password').toString('base64')}`
+});
+setGlobalDispatcher(proxyAgent);
+
+const { statusCode, body } = await request('http://localhost:3000/foo');
+
+console.log('response received', statusCode); // response received 200
+
+for await (const data of body) {
+  console.log('data', data.toString('utf8')); // data foo
+}
+```
+
+### `ProxyAgent.close()`
+
+Closes the proxy agent and waits for registered pools and clients to also close before resolving.
+
+Returns: `Promise<void>`
+
+#### Example - clean up after tests are complete
+
+```js
+import { ProxyAgent, setGlobalDispatcher } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+setGlobalDispatcher(proxyAgent)
+
+await proxyAgent.close()
+```
+
+### `ProxyAgent.dispatch(options, handlers)`
+
+Implements [`Agent.dispatch(options, handlers)`](/docs/docs/api/Agent.md#parameter-agentdispatchoptions).
+
+### `ProxyAgent.request(options[, callback])`
+
+See [`Dispatcher.request(options [, callback])`](/docs/docs/api/Dispatcher.md#dispatcherrequestoptions-callback).
+
+
+#### Example - ProxyAgent with Fetch
+
+This example demonstrates how to use `fetch` with a proxy via `ProxyAgent`. It is particularly useful for scenarios requiring proxy tunneling.
+
+```javascript
+import { ProxyAgent, fetch } from 'undici';
+
+// Define the ProxyAgent
+const proxyAgent = new ProxyAgent('http://localhost:8000');
+
+// Make a GET request through the proxy
+const response = await fetch('http://localhost:3000/foo', {
+  dispatcher: proxyAgent,
+  method: 'GET',
+});
+
+console.log('Response status:', response.status);
+console.log('Response data:', await response.text());
+```
+
+---
+
+#### Example - ProxyAgent with a Custom Proxy Server
+
+This example shows how to create a custom proxy server and use it with `ProxyAgent`.
+
+```javascript
+import * as http from 'node:http';
+import { createProxy } from 'proxy';
+import { ProxyAgent, fetch } from 'undici';
+
+// Create a proxy server
+const proxyServer = createProxy(http.createServer());
+proxyServer.listen(8000, () => {
+  console.log('Proxy server running on port 8000');
+});
+
+// Define and use the ProxyAgent
+const proxyAgent = new ProxyAgent('http://localhost:8000');
+
+const response = await fetch('http://example.com', {
+  dispatcher: proxyAgent,
+  method: 'GET',
+});
+
+console.log('Response status:', response.status);
+console.log('Response data:', await response.text());
+```
+
+---
+
+#### Example - ProxyAgent with HTTPS Tunneling
+
+This example demonstrates how to perform HTTPS tunneling using a proxy.
+
+```javascript
+import { ProxyAgent, fetch } from 'undici';
+
+// Define a ProxyAgent for HTTPS proxy
+const proxyAgent = new ProxyAgent('https://secure.proxy.server');
+
+// Make a request to an HTTPS endpoint via the proxy
+const response = await fetch('https://secure.endpoint.com/api/data', {
+  dispatcher: proxyAgent,
+  method: 'GET',
+});
+
+console.log('Response status:', response.status);
+console.log('Response data:', await response.json());
+```
+
+#### Example - ProxyAgent as a Global Dispatcher
+
+`ProxyAgent` can be configured as a global dispatcher, making it available for all requests without explicitly passing it. This simplifies code and is useful when a single proxy configuration applies to all requests.
+
+```javascript
+import { ProxyAgent, setGlobalDispatcher, fetch } from 'undici';
+
+// Define and configure the ProxyAgent
+const proxyAgent = new ProxyAgent('http://localhost:8000');
+setGlobalDispatcher(proxyAgent);
+
+// Make requests without specifying the dispatcher
+const response = await fetch('http://example.com');
+console.log('Response status:', response.status);
+console.log('Response data:', await response.text());

+# SnapshotAgent
+
+The `SnapshotAgent` provides a powerful way to record and replay HTTP requests for testing purposes. It extends `MockAgent` to enable automatic snapshot testing, eliminating the need to manually define mock responses.
+
+## Use Cases
+
+- **Integration Testing**: Record real API interactions and replay them in tests
+- **Offline Development**: Work with APIs without network connectivity
+- **Consistent Test Data**: Ensure tests use the same responses across runs
+- **API Contract Testing**: Capture and validate API behavior over time
+
+## Constructor
+
+```javascript
+new SnapshotAgent([options])
+```
+
+### Parameters
+
+- **options** `Object` (optional)
+  - **mode** `String` - The snapshot mode: `'record'`, `'playback'`, or `'update'`. Default: `'record'`
+  - **snapshotPath** `String` - Path to the snapshot file for loading/saving
+  - **maxSnapshots** `Number` - Maximum number of snapshots to keep in memory. Default: `Infinity`
+  - **autoFlush** `Boolean` - Whether to automatically save snapshots to disk. Default: `false`
+  - **flushInterval** `Number` - Interval in milliseconds for auto-flush. Default: `30000`
+  - **matchHeaders** `Array<String>` - Specific headers to include in request matching. Default: all headers
+  - **ignoreHeaders** `Array<String>` - Headers to ignore during request matching
+  - **excludeHeaders** `Array<String>` - Headers to exclude from snapshots (for security)
+  - **matchBody** `Boolean` - Whether to include request body in matching. Default: `true`
+  - **matchQuery** `Boolean` - Whether to include query parameters in matching. Default: `true`
+  - **caseSensitive** `Boolean` - Whether header matching is case-sensitive. Default: `false`
+  - **shouldRecord** `Function` - Callback to determine if a request should be recorded
+  - **shouldPlayback** `Function` - Callback to determine if a request should be played back
+  - **excludeUrls** `Array` - URL patterns (strings or RegExp) to exclude from recording/playback
+  - All other options from `MockAgent` are supported
+
+### Modes
+
+#### Record Mode (`'record'`)
+Makes real HTTP requests and saves the responses to snapshots.
+
+```javascript
+import { SnapshotAgent, setGlobalDispatcher } from 'undici'
+
+const agent = new SnapshotAgent({ 
+  mode: 'record',
+  snapshotPath: './test/snapshots/api-calls.json'
+})
+setGlobalDispatcher(agent)
+
+// Makes real requests and records them
+const response = await fetch('https://api.example.com/users')
+const users = await response.json()
+
+// Save recorded snapshots
+await agent.saveSnapshots()
+```
+
+#### Playback Mode (`'playback'`)
+Replays recorded responses without making real HTTP requests.
+
+```javascript
+import { SnapshotAgent, setGlobalDispatcher } from 'undici'
+
+const agent = new SnapshotAgent({
+  mode: 'playback',
+  snapshotPath: './test/snapshots/api-calls.json'
+})
+setGlobalDispatcher(agent)
+
+// Uses recorded response instead of real request
+const response = await fetch('https://api.example.com/users')
+```
+
+#### Update Mode (`'update'`)
+Uses existing snapshots when available, but records new ones for missing requests.
+
+```javascript
+import { SnapshotAgent, setGlobalDispatcher } from 'undici'
+
+const agent = new SnapshotAgent({
+  mode: 'update',
+  snapshotPath: './test/snapshots/api-calls.json'
+})
+setGlobalDispatcher(agent)
+
+// Uses snapshot if exists, otherwise makes real request and records it
+const response = await fetch('https://api.example.com/new-endpoint')
+```
+
+## Instance Methods
+
+### `agent.saveSnapshots([filePath])`
+
+Saves all recorded snapshots to a file.
+
+#### Parameters
+
+- **filePath** `String` (optional) - Path to save snapshots. Uses constructor `snapshotPath` if not provided.
+
+#### Returns
+
+`Promise<void>`
+
+```javascript
+await agent.saveSnapshots('./custom-snapshots.json')
+```
+
+## Advanced Configuration
+
+### Header Filtering
+
+Control which headers are used for request matching and what gets stored in snapshots:
+
+```javascript
+const agent = new SnapshotAgent({
+  mode: 'record',
+  snapshotPath: './snapshots.json',
+  
+  // Only match these specific headers
+  matchHeaders: ['content-type', 'accept'],
+  
+  // Ignore these headers during matching (but still store them)
+  ignoreHeaders: ['user-agent', 'date'],
+  
+  // Exclude sensitive headers from snapshots entirely
+  excludeHeaders: ['authorization', 'x-api-key', 'cookie']
+})
+```
+
+### Custom Request/Response Filtering
+
+Use callback functions to determine what gets recorded or played back:
+
+```javascript
+const agent = new SnapshotAgent({
+  mode: 'record',
+  snapshotPath: './snapshots.json',
+  
+  // Only record GET requests to specific endpoints
+  shouldRecord: (requestOpts) => {
+    const url = new URL(requestOpts.path, requestOpts.origin)
+    return requestOpts.method === 'GET' && url.pathname.startsWith('/api/v1/')
+  },
+  
+  // Skip authentication endpoints during playback
+  shouldPlayback: (requestOpts) => {
+    const url = new URL(requestOpts.path, requestOpts.origin)
+    return !url.pathname.includes('/auth/')
+  }
+})
+```
+
+### URL Pattern Exclusion
+
+Exclude specific URLs from recording/playback using patterns:
+
+```javascript
+const agent = new SnapshotAgent({
+  mode: 'record',
+  snapshotPath: './snapshots.json',
+  
+  excludeUrls: [
+    'https://analytics.example.com',  // String match
+    /\/api\/v\d+\/health/,           // Regex pattern
+    'telemetry'                      // Substring match
+  ]
+})
+```
+
+### Memory Management
+
+Configure automatic memory and disk management:
+
+```javascript
+const agent = new SnapshotAgent({
+  mode: 'record',
+  snapshotPath: './snapshots.json',
+  
+  // Keep only 1000 snapshots in memory
+  maxSnapshots: 1000,
+  
+  // Automatically save to disk every 30 seconds
+  autoFlush: true,
+  flushInterval: 30000
+})
+```
+
+### Sequential Response Handling
+
+Handle multiple responses for the same request (similar to nock):
+
+```javascript
+// In record mode, multiple identical requests get recorded as separate responses
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './sequential.json' })
+
+// First call returns response A
+await fetch('https://api.example.com/random')
+
+// Second call returns response B  
+await fetch('https://api.example.com/random')
+
+await agent.saveSnapshots()
+
+// In playback mode, calls return responses in sequence
+const playbackAgent = new SnapshotAgent({ mode: 'playback', snapshotPath: './sequential.json' })
+
+// Returns response A
+const first = await fetch('https://api.example.com/random')
+
+// Returns response B
+const second = await fetch('https://api.example.com/random')
+
+// Third call repeats the last response (B)
+const third = await fetch('https://api.example.com/random')
+```
+
+## Managing Snapshots
+
+### Replacing Existing Snapshots
+
+```javascript
+// Load existing snapshots
+await agent.loadSnapshots('./old-snapshots.json')
+
+// Get snapshot data
+const recorder = agent.getRecorder()
+const snapshots = recorder.getSnapshots()
+
+// Modify or filter snapshots
+const filteredSnapshots = snapshots.filter(s => 
+  !s.request.url.includes('deprecated')
+)
+
+// Replace all snapshots
+agent.replaceSnapshots(filteredSnapshots.map((snapshot, index) => ({
+  hash: `new-hash-${index}`,
+  snapshot
+})))
+
+// Save updated snapshots
+await agent.saveSnapshots('./updated-snapshots.json')
+```
+
+### `agent.loadSnapshots([filePath])`
+
+Loads snapshots from a file.
+
+#### Parameters
+
+- **filePath** `String` (optional) - Path to load snapshots from. Uses constructor `snapshotPath` if not provided.
+
+#### Returns
+
+`Promise<void>`
+
+```javascript
+await agent.loadSnapshots('./existing-snapshots.json')
+```
+
+### `agent.getRecorder()`
+
+Gets the underlying `SnapshotRecorder` instance.
+
+#### Returns
+
+`SnapshotRecorder`
+
+```javascript
+const recorder = agent.getRecorder()
+console.log(`Recorded ${recorder.size()} interactions`)
+```
+
+### `agent.getMode()`
+
+Gets the current snapshot mode.
+
+#### Returns
+
+`String` - The current mode (`'record'`, `'playback'`, or `'update'`)
+
+### `agent.clearSnapshots()`
+
+Clears all recorded snapshots from memory.
+
+```javascript
+agent.clearSnapshots()
+```
+
+## Working with Different Request Types
+
+### GET Requests
+
+```javascript
+// Record mode
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './get-snapshots.json' })
+setGlobalDispatcher(agent)
+
+const response = await fetch('https://jsonplaceholder.typicode.com/posts/1')
+const post = await response.json()
+
+await agent.saveSnapshots()
+```
+
+### POST Requests with Body
+
+```javascript
+// Record mode
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './post-snapshots.json' })
+setGlobalDispatcher(agent)
+
+const response = await fetch('https://jsonplaceholder.typicode.com/posts', {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({ title: 'Test Post', body: 'Content' })
+})
+
+await agent.saveSnapshots()
+```
+
+### Using with `undici.request`
+
+SnapshotAgent works with all undici APIs, not just fetch:
+
+```javascript
+import { SnapshotAgent, request, setGlobalDispatcher } from 'undici'
+
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './request-snapshots.json' })
+setGlobalDispatcher(agent)
+
+const { statusCode, headers, body } = await request('https://api.example.com/data')
+const data = await body.json()
+
+await agent.saveSnapshots()
+```
+
+## Test Integration
+
+### Basic Test Setup
+
+```javascript
+import { test } from 'node:test'
+import { SnapshotAgent, setGlobalDispatcher, getGlobalDispatcher } from 'undici'
+
+test('API integration test', async (t) => {
+  const originalDispatcher = getGlobalDispatcher()
+  
+  const agent = new SnapshotAgent({
+    mode: 'playback',
+    snapshotPath: './test/snapshots/api-test.json'
+  })
+  setGlobalDispatcher(agent)
+  
+  t.after(() => setGlobalDispatcher(originalDispatcher))
+  
+  // This will use recorded data
+  const response = await fetch('https://api.example.com/users')
+  const users = await response.json()
+  
+  assert(Array.isArray(users))
+  assert(users.length > 0)
+})
+```
+
+### Environment-Based Mode Selection
+
+```javascript
+const mode = process.env.SNAPSHOT_MODE || 'playback'
+
+const agent = new SnapshotAgent({
+  mode,
+  snapshotPath: './test/snapshots/integration.json'
+})
+
+// Run with: SNAPSHOT_MODE=record npm test (to record)
+// Run with: npm test (to playback)
+```
+
+### Test Helper Function
+
+```javascript
+function createSnapshotAgent(testName, mode = 'playback') {
+  return new SnapshotAgent({
+    mode,
+    snapshotPath: `./test/snapshots/${testName}.json`
+  })
+}
+
+test('user API test', async (t) => {
+  const agent = createSnapshotAgent('user-api')
+  setGlobalDispatcher(agent)
+  
+  // Test implementation...
+})
+```
+
+## Snapshot File Format
+
+Snapshots are stored as JSON with the following structure:
+
+```json
+[
+  {
+    "hash": "dGVzdC1oYXNo...",
+    "snapshot": {
+      "request": {
+        "method": "GET",
+        "url": "https://api.example.com/users",
+        "headers": {
+          "authorization": "Bearer token"
+        },
+        "body": undefined
+      },
+      "response": {
+        "statusCode": 200,
+        "headers": {
+          "content-type": "application/json"
+        },
+        "body": "eyJkYXRhIjoidGVzdCJ9", // base64 encoded
+        "trailers": {}
+      },
+      "timestamp": "2024-01-01T00:00:00.000Z"
+    }
+  }
+]
+```
+
+## Security Considerations
+
+### Sensitive Data in Snapshots
+
+By default, SnapshotAgent records all headers and request/response data. For production use, always exclude sensitive information:
+
+```javascript
+const agent = new SnapshotAgent({
+  mode: 'record',
+  snapshotPath: './snapshots.json',
+  
+  // Exclude sensitive headers from snapshots
+  excludeHeaders: [
+    'authorization',
+    'x-api-key', 
+    'cookie',
+    'set-cookie',
+    'x-auth-token',
+    'x-csrf-token'
+  ],
+  
+  // Filter out requests with sensitive data
+  shouldRecord: (requestOpts) => {
+    const url = new URL(requestOpts.path, requestOpts.origin)
+    
+    // Don't record authentication endpoints
+    if (url.pathname.includes('/auth/') || url.pathname.includes('/login')) {
+      return false
+    }
+    
+    // Don't record if request contains sensitive body data
+    if (requestOpts.body && typeof requestOpts.body === 'string') {
+      const body = requestOpts.body.toLowerCase()
+      if (body.includes('password') || body.includes('secret')) {
+        return false
+      }
+    }
+    
+    return true
+  }
+})
+```
+
+### Snapshot File Security
+
+**Important**: Snapshot files may contain sensitive data. Handle them securely:
+
+- ✅ Add snapshot files to `.gitignore` if they contain real API data
+- ✅ Use environment-specific snapshots (dev/staging/prod)
+- ✅ Regularly review snapshot contents for sensitive information
+- ✅ Use the `excludeHeaders` option for production snapshots
+- ❌ Never commit snapshots with real authentication tokens
+- ❌ Don't share snapshot files containing personal data
+
+```gitignore
+# Exclude snapshots with real data
+/test/snapshots/production-*.json
+/test/snapshots/*-real-data.json
+
+# Include sanitized test snapshots
+!/test/snapshots/mock-*.json
+```
+
+## Error Handling
+
+### Missing Snapshots in Playback Mode
+
+```javascript
+try {
+  const response = await fetch('https://api.example.com/nonexistent')
+} catch (error) {
+  if (error.message.includes('No snapshot found')) {
+    // Handle missing snapshot
+    console.log('Snapshot not found for this request')
+  }
+}
+```
+
+### Handling Network Errors in Record Mode
+
+```javascript
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './snapshots.json' })
+
+try {
+  const response = await fetch('https://nonexistent-api.example.com/data')
+} catch (error) {
+  // Network errors are not recorded as snapshots
+  console.log('Network error:', error.message)
+}
+```
+
+## Best Practices
+
+### 1. Organize Snapshots by Test Suite
+
+```javascript
+// Use descriptive snapshot file names
+const agent = new SnapshotAgent({
+  mode: 'playback',
+  snapshotPath: `./test/snapshots/${testSuiteName}-${testName}.json`
+})
+```
+
+### 2. Version Control Snapshots
+
+Add snapshot files to version control to ensure consistent test behavior across environments:
+
+```gitignore
+# Include snapshots in version control
+!/test/snapshots/*.json
+```
+
+### 3. Clean Up Test Data
+
+```javascript
+test('API test', async (t) => {
+  const agent = new SnapshotAgent({
+    mode: 'playback',
+    snapshotPath: './test/snapshots/temp-test.json'
+  })
+  
+  // Clean up after test
+  t.after(() => {
+    agent.clearSnapshots()
+  })
+})
+```
+
+### 4. Snapshot Validation
+
+```javascript
+test('validate snapshot contents', async (t) => {
+  const agent = new SnapshotAgent({
+    mode: 'playback',
+    snapshotPath: './test/snapshots/validation.json'
+  })
+  
+  const recorder = agent.getRecorder()
+  const snapshots = recorder.getSnapshots()
+  
+  // Validate snapshot structure
+  assert(snapshots.length > 0, 'Should have recorded snapshots')
+  assert(snapshots[0].request.url.startsWith('https://'), 'Should use HTTPS')
+})
+```
+
+## Comparison with Other Tools
+
+### vs Manual MockAgent Setup
+
+**Manual MockAgent:**
+```javascript
+const mockAgent = new MockAgent()
+const mockPool = mockAgent.get('https://api.example.com')
+
+mockPool.intercept({
+  path: '/users',
+  method: 'GET'
+}).reply(200, [
+  { id: 1, name: 'User 1' },
+  { id: 2, name: 'User 2' }
+])
+```
+
+**SnapshotAgent:**
+```javascript
+// Record once
+const agent = new SnapshotAgent({ mode: 'record', snapshotPath: './snapshots.json' })
+// Real API call gets recorded automatically
+
+// Use in tests
+const agent = new SnapshotAgent({ mode: 'playback', snapshotPath: './snapshots.json' })
+// Automatically replays recorded response
+```
+
+### vs nock
+
+SnapshotAgent provides similar functionality to nock but is specifically designed for undici:
+
+- ✅ Works with all undici APIs (`request`, `stream`, `pipeline`, etc.)
+- ✅ Supports undici-specific features (RetryAgent, connection pooling)
+- ✅ Better TypeScript integration
+- ✅ More efficient for high-performance scenarios

+# Class: WebSocket
+
+Extends: [`EventTarget`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget)
+
+The WebSocket object provides a way to manage a WebSocket connection to a server, allowing bidirectional communication. The API follows the [WebSocket spec](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) and [RFC 6455](https://datatracker.ietf.org/doc/html/rfc6455).
+
+## `new WebSocket(url[, protocol])`
+
+Arguments:
+
+* **url** `URL | string`
+* **protocol** `string | string[] | WebSocketInit` (optional) - Subprotocol(s) to request the server use, or a [`Dispatcher`](/docs/docs/api/Dispatcher.md).
+
+### Example:
+
+This example will not work in browsers or other platforms that don't allow passing an object.
+
+```mjs
+import { WebSocket, ProxyAgent } from 'undici'
+
+const proxyAgent = new ProxyAgent('my.proxy.server')
+
+const ws = new WebSocket('wss://echo.websocket.events', {
+  dispatcher: proxyAgent,
+  protocols: ['echo', 'chat']
+})
+```
+
+If you do not need a custom Dispatcher, it's recommended to use the following pattern:
+
+```mjs
+import { WebSocket } from 'undici'
+
+const ws = new WebSocket('wss://echo.websocket.events', ['echo', 'chat'])
+```
+
+# Class: WebSocketStream
+
+> ⚠️ Warning: the WebSocketStream API has not been finalized and is likely to change.
+
+See [MDN](https://developer.mozilla.org/en-US/docs/Web/API/WebSocketStream) for more information.
+
+## `new WebSocketStream(url[, protocol])`
+
+Arguments:
+
+* **url** `URL | string`
+* **options** `WebSocketStreamOptions` (optional)
+
+### WebSocketStream Example
+
+```js
+const stream = new WebSocketStream('https://echo.websocket.org/')
+const { readable, writable } = await stream.opened
+
+async function read () {
+  /** @type {ReadableStreamReader} */
+  const reader = readable.getReader()
+
+  while (true) {
+    const { done, value } = await reader.read()
+    if (done) break
+
+    // do something with value
+  }
+}
+
+async function write () {
+  /** @type {WritableStreamDefaultWriter} */
+  const writer = writable.getWriter()
+  writer.write('Hello, world!')
+  writer.releaseLock()
+}
+
+read()
+
+setInterval(() => write(), 5000)
+
+```
+
+## ping(websocket, payload)
+Arguments:
+
+* **websocket** `WebSocket` - The WebSocket instance to send the ping frame on
+* **payload** `Buffer|undefined` (optional) - Optional payload data to include with the ping frame. Must not exceed 125 bytes.
+
+Sends a ping frame to the WebSocket server. The server must respond with a pong frame containing the same payload data. This can be used for keepalive purposes or to verify that the connection is still active.
+
+### Example:
+
+```js
+import { WebSocket, ping } from 'undici'
+
+const ws = new WebSocket('wss://echo.websocket.events')
+
+ws.addEventListener('open', () => {
+  // Send ping with no payload
+  ping(ws)
+
+  // Send ping with payload
+  const payload = Buffer.from('hello')
+  ping(ws, payload)
+})
+```
+
+**Note**: A ping frame cannot have a payload larger than 125 bytes. The ping will only be sent if the WebSocket connection is in the OPEN state.

+# Client Lifecycle
+
+An Undici [Client](/docs/docs/api/Client.md) can be best described as a state machine. The following list is a summary of the various state transitions the `Client` will go through in its lifecycle. This document also contains detailed breakdowns of each state.
+
+> This diagram is not a perfect representation of the undici Client. Since the Client class is not actually implemented as a state-machine, actual execution may deviate slightly from what is described below. Consider this as a general resource for understanding the inner workings of the Undici client rather than some kind of formal specification.
+
+## State Transition Overview
+
+* A `Client` begins in the **idle** state with no socket connection and no requests in queue.
+  * The *connect* event transitions the `Client` to the **pending** state where requests can be queued prior to processing.
+  * The *close* and *destroy* events transition the `Client` to the **destroyed** state. Since there are no requests in the queue, the *close* event immediately transitions to the **destroyed** state.
+* The **pending** state indicates the underlying socket connection has been successfully established and requests are queueing.
+  * The *process* event transitions the `Client` to the **processing** state where requests are processed.
+  * If requests are queued, the *close* event transitions to the **processing** state; otherwise, it transitions to the **destroyed** state.
+  * The *destroy* event transitions to the **destroyed** state.
+* The **processing** state initializes to the **processing.running** state.
+  * If the current request requires draining, the *needDrain* event transitions the `Client` into the **processing.busy** state which will return to the **processing.running** state with the *drainComplete* event.
+  * After all queued requests are completed, the *keepalive* event transitions the `Client` back to the **pending** state. If no requests are queued during the timeout, the **close** event transitions the `Client` to the **destroyed** state.
+  * If the *close* event is fired while the `Client` still has queued requests, the `Client` transitions to the **process.closing** state where it will complete all existing requests before firing the *done* event.
+  * The *done* event gracefully transitions the `Client` to the **destroyed** state.
+  * At any point in time, the *destroy* event will transition the `Client` from the **processing** state to the **destroyed** state, destroying any queued requests.
+* The **destroyed** state is a final state and the `Client` is no longer functional.
+
+A state diagram representing an Undici Client instance:
+
+```mermaid
+stateDiagram-v2
+  [*] --> idle
+  idle --> pending : connect
+  idle --> destroyed : destroy/close

+      running --> busy : needDrain
+      busy --> running : drainComplete
+      running --> [*] : keepalive
+      closing --> [*] : done
+  }
+```
+## State details
+
+### idle
+
+The **idle** state is the initial state of a `Client` instance. While an `origin` is required for instantiating a `Client` instance, the underlying socket connection will not be established until a request is queued using [`Client.dispatch()`](/docs/docs/api/Client.md#clientdispatchoptions-handlers). By calling `Client.dispatch()` directly or using one of the multiple implementations ([`Client.connect()`](Client.md#clientconnectoptions-callback), [`Client.pipeline()`](Client.md#clientpipelineoptions-handler), [`Client.request()`](Client.md#clientrequestoptions-callback), [`Client.stream()`](Client.md#clientstreamoptions-factory-callback), and [`Client.upgrade()`](/docs/docs/api/Client.md#clientupgradeoptions-callback)), the `Client` instance will transition from **idle** to [**pending**](/docs/docs/api/Client.md#pending) and then most likely directly to [**processing**](/docs/docs/api/Client.md#processing).
+
+Calling [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) or [`Client.destroy()`](Client.md#clientdestroyerror-callback) transitions directly to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state since the `Client` instance will have no queued requests in this state.

+The **pending** state signifies a non-processing `Client`. Upon entering this state, the `Client` establishes a socket connection and emits the [`'connect'`](/docs/docs/api/Client.md#event-connect) event signalling a connection was successfully established with the `origin` provided during `Client` instantiation. The internal queue is initially empty, and requests can start queueing.
+
+Calling [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) with queued requests, transitions the `Client` to the [**processing**](/docs/docs/api/Client.md#processing) state. Without queued requests, it transitions to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state.
+
+Calling [`Client.destroy()`](/docs/docs/api/Client.md#clientdestroyerror-callback) transitions directly to the [**destroyed**](/docs/docs/api/Client.md#destroyed) state regardless of existing requests.
+
+### processing
+
+The **processing** state is a state machine within itself. It initializes to the [**processing.running**](/docs/docs/api/Client.md#running) state. The [`Client.dispatch()`](/docs/docs/api/Client.md#clientdispatchoptions-handlers), [`Client.close()`](Client.md#clientclosecallback), and [`Client.destroy()`](Client.md#clientdestroyerror-callback) can be called at any time while the `Client` is in this state. `Client.dispatch()` will add more requests to the queue while existing requests continue to be processed. `Client.close()` will transition to the [**processing.closing**](/docs/docs/api/Client.md#closing) state. And `Client.destroy()` will transition to [**destroyed**](/docs/docs/api/Client.md#destroyed).
+
+#### running
+
+In the **processing.running** sub-state, queued requests are being processed in a FIFO order. If a request body requires draining, the *needDrain* event transitions to the [**processing.busy**](/docs/docs/api/Client.md#busy) sub-state. The *close* event transitions the Client to the [**process.closing**](/docs/docs/api/Client.md#closing) sub-state. If all queued requests are processed and neither [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) nor [`Client.destroy()`](Client.md#clientdestroyerror-callback) are called, then the [**processing**](/docs/docs/api/Client.md#processing) machine will trigger a *keepalive* event transitioning the `Client` back to the [**pending**](/docs/docs/api/Client.md#pending) state. During this time, the `Client` is waiting for the socket connection to timeout, and once it does, it triggers the *timeout* event and transitions to the [**idle**](/docs/docs/api/Client.md#idle) state.
+
+#### busy
+
+This sub-state is only entered when a request body is an instance of [Stream](https://nodejs.org/api/stream.html) and requires draining. The `Client` cannot process additional requests while in this state and must wait until the currently processing request body is completely drained before transitioning back to [**processing.running**](/docs/docs/api/Client.md#running).
+
+#### closing
+
+This sub-state is only entered when a `Client` instance has queued requests and the [`Client.close()`](/docs/docs/api/Client.md#clientclosecallback) method is called. In this state, the `Client` instance continues to process requests as usual, with the one exception that no additional requests can be queued. Once all of the queued requests are processed, the `Client` will trigger the *done* event gracefully entering the [**destroyed**](/docs/docs/api/Client.md#destroyed) state without an error.
+
+### destroyed
+
+The **destroyed** state is a final state for the `Client` instance. Once in this state, a `Client` is nonfunctional. Calling any other `Client` methods will result in an `ClientDestroyedError`.

+# Client certificate
+
+Client certificate authentication can be configured with the `Client`, the required options are passed along through the `connect` option.
+
+The client certificates must be signed by a trusted CA. The Node.js default is to trust the well-known CAs curated by Mozilla.
+
+Setting the server option `requestCert: true` tells the server to request the client certificate.
+
+The server option `rejectUnauthorized: false` allows us to handle any invalid certificate errors in client code. The `authorized` property on the socket of the incoming request will show if the client certificate was valid. The `authorizationError` property will give the reason if the certificate was not valid.

+# Mocking Request
+
+Undici has its own mocking [utility](/docs/docs/api/MockAgent.md). It allow us to intercept undici HTTP requests and return mocked values instead. It can be useful for testing purposes.
+
+Example:
+
+```js
+// bank.mjs
+import { request } from 'undici'
+
+export async function bankTransfer(recipient, amount) {
+  const { body } = await request('http://localhost:3000/bank-transfer',
+    {
+      method: 'POST',
+      headers: {
+        'X-TOKEN-SECRET': 'SuperSecretToken',
+      },
+      body: JSON.stringify({
+        recipient,
+        amount
+      })
+    }
+  )
+  return await body.json()
+}
+```
+
+And this is what the test file looks like:
+
+```js
+// index.test.mjs
+import { strict as assert } from 'node:assert'
+import { MockAgent, setGlobalDispatcher, } from 'undici'
+import { bankTransfer } from './bank.mjs'
+
+const mockAgent = new MockAgent();
+
+setGlobalDispatcher(mockAgent);
+
+// Provide the base url to the request
+const mockPool = mockAgent.get('http://localhost:3000');
+
+// intercept the request
+mockPool.intercept({
+  path: '/bank-transfer',
+  method: 'POST',
+  headers: {
+    'X-TOKEN-SECRET': 'SuperSecretToken',
+  },
+  body: JSON.stringify({
+    recipient: '1234567890',
+    amount: '100'
+  })
+}).reply(200, {
+  message: 'transaction processed'
+})
+
+const success = await bankTransfer('1234567890', '100')
+
+assert.deepEqual(success, { message: 'transaction processed' })
+
+// if you dont want to check whether the body or the headers contain the same value
+// just remove it from interceptor
+mockPool.intercept({
+  path: '/bank-transfer',
+  method: 'POST',
+}).reply(400, {
+  message: 'bank account not found'
+})
+
+const badRequest = await bankTransfer('1234567890', '100')
+
+assert.deepEqual(badRequest, { message: 'bank account not found' })
+```

+
+## Access agent call history
+
+Using a MockAgent also allows you to make assertions on the configuration used to make your request in your application.
+
+Here is an example :
+
+```js
+// index.test.mjs
+import { strict as assert } from 'node:assert'
+import { MockAgent, setGlobalDispatcher, fetch } from 'undici'
+import { app } from './app.mjs'
+
+// given an application server running on http://localhost:3000
+await app.start()
+
+// enable call history at instantiation
+const mockAgent = new MockAgent({ enableCallHistory: true })
+// or after instantiation
+mockAgent.enableCallHistory()
+
+setGlobalDispatcher(mockAgent)
+
+// this call is made (not intercepted)
+await fetch(`http://localhost:3000/endpoint?query='hello'`, {
+  method: 'POST',
+  headers: { 'content-type': 'application/json' }
+  body: JSON.stringify({ data: '' })
+})
+
+// access to the call history of the MockAgent (which register every call made intercepted or not)
+assert.ok(mockAgent.getCallHistory()?.calls().length === 1)
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.fullUrl, `http://localhost:3000/endpoint?query='hello'`)
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.body, JSON.stringify({ data: '' }))
+assert.deepStrictEqual(mockAgent.getCallHistory()?.firstCall()?.searchParams, { query: 'hello' })
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.port, '3000')
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.host, 'localhost:3000')
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.method, 'POST')
+assert.strictEqual(mockAgent.getCallHistory()?.firstCall()?.path, '/endpoint')
+assert.deepStrictEqual(mockAgent.getCallHistory()?.firstCall()?.headers, { 'content-type': 'application/json' })
+
+// clear all call history logs
+mockAgent.clearCallHistory()
+
+assert.ok(mockAgent.getCallHistory()?.calls().length === 0)
+```
+
+Calling `mockAgent.close()` will automatically clear and delete every call history for you.

+
+Explore other MockCallHistoryLog functionality [here](/docs/docs/api/MockCallHistoryLog.md)
+
+## Debug Mock Value
+
+When the interceptor and the request options are not the same, undici will automatically make a real HTTP request. To prevent real requests from being made, use `mockAgent.disableNetConnect()`:
+
+```js
+const mockAgent = new MockAgent();
+
+setGlobalDispatcher(mockAgent);
+mockAgent.disableNetConnect()
+
+// Provide the base url to the request
+const mockPool = mockAgent.get('http://localhost:3000');
+
+mockPool.intercept({
+  path: '/bank-transfer',
+  method: 'POST',
+}).reply(200, {
+  message: 'transaction processed'
+})
+
+const badRequest = await bankTransfer('1234567890', '100')
+// Will throw an error
+// MockNotMatchedError: Mock dispatch not matched for path '/bank-transfer':
+// subsequent request to origin http://localhost:3000 was not allowed (net.connect disabled)
+```
+
+## Reply with data based on request
+
+If the mocked response needs to be dynamically derived from the request parameters, you can provide a function instead of an object to `reply`:
+
+```js
+mockPool.intercept({
+  path: '/bank-transfer',
+  method: 'POST',
+  headers: {
+    'X-TOKEN-SECRET': 'SuperSecretToken',
+  },
+  body: JSON.stringify({
+    recipient: '1234567890',
+    amount: '100'
+  })
+}).reply(200, (opts) => {
+  // do something with opts
+
+  return { message: 'transaction processed' }
+})
+```
+
+in this case opts will be
+
+```
+{
+  method: 'POST',
+  headers: { 'X-TOKEN-SECRET': 'SuperSecretToken' },
+  body: '{"recipient":"1234567890","amount":"100"}',
+  origin: 'http://localhost:3000',
+  path: '/bank-transfer'
+}
+```

+# Connecting through a proxy
+
+Connecting through a proxy is possible by:

+- Using [ProxyAgent](/docs/docs/api/ProxyAgent.md).
+- Configuring `Client` or `Pool` constructor.
+
+The proxy url should be passed to the `Client` or `Pool` constructor, while the upstream server url
+should be added to every request call in the `path`.
+For instance, if you need to send a request to the `/hello` route of your upstream server,

+Undici is tuned for a production use case and its default will keep
