|
| ## 🎨 Client Integration |
|
|
| ### JavaScript/TypeScript |
| ```typescript |
| // Get all resources |
| const response = await fetch('/api/resources/database?source=all'); |
| const data = await response.json(); |
| |
| // Search resources |
| const searchResults = await fetch('/api/resources/database/search?q=coingecko'); |
| const found = await searchResults.json(); |
| |
| // Get random resources for discovery |
| const random = await fetch('/api/resources/database/random?count=10'); |
| const randomResources = await random.json(); |
| ``` |
|
|
| ### Python |
| ```python |
| import requests |
| |
| # Get database stats |
| stats = requests.get('https://your-api.hf.space/api/resources/database/stats') |
| print(f"Total resources: {stats.json()['overview']['total_resources']}") |
| |
| # Search for Binance resources |
| search = requests.get( |
| 'https://your-api.hf.space/api/resources/database/search', |
| params={'q': 'binance', 'limit': 10} |
| ) |
| print(search.json()) |
| ``` |
|
|

|
|
| ## 🔧 Advanced Use Cases |
|
|
| ### 1. Build a Resource Directory UI |
| ```javascript |
| // Fetch all categories |
| const categories = await fetch('/api/resources/database/categories'); |
| const cats = await categories.json(); |
| |
| // For each category, fetch resources |
| for (const category of cats.unified_resources.categories) { |
| const resources = await fetch( |
| `/api/resources/database/category/${category}?limit=100` |
| ); |
| // Display in UI |
| } |
| ``` |
|
|
| ### 2. Resource Discovery Dashboard |
| ```javascript |
| // Get random resources every 5 seconds for discovery |
| setInterval(async () => { |
| const random = await fetch('/api/resources/database/random?count=3'); |
| const resources = await random.json(); |
| displayResources(resources.resources); |
| }, 5000); |
| ``` |
|
|
| ### 3. Smart Resource Selection |
| ```javascript |
| // Find best resource for a specific use case |
| const search = await fetch( |
| '/api/resources/database/search?q=price&fields=name,desc&limit=50' |
| ); |
| const results = await search.json(); |
| |
| // Filter by criteria |
| const freeAPIs = results.results.filter(r => |
| r.resource.free === true || |
| r.resource.auth?.type === "none" |
| ); |
| ``` |

|
|
| ### Adding New Resources |
| To add new resources to the database: |
|
|
| 1. Update the JSON files in `api-resources/` |
| 2. Follow the schema format |
| 3. Restart the server |
| 4. Resources will be automatically loaded |
