# zai2api

OpenAI-compatible chat/completion proxy backed by `https://chat.z.ai/`.

## Features

- Supports `POST /v1/chat/completions`
- Supports `POST /v1/responses`
- Creates a fresh upstream chat for every request
- Preserves reasoning output separately from final answer text
- Reuses `ZAI_SESSION_TOKEN` directly or refreshes it from `ZAI_JWT`

## Requirements

- Python 3.12+
- `uv`
- One of:
  - `ZAI_JWT`
  - `ZAI_SESSION_TOKEN`

## Run

```bash
export ZAI_JWT='your-jwt'
uv run python -m zai2api
```

Or with the installed script:

```bash
export ZAI_JWT='your-jwt'
uv run zai2api
```

Default bind address is `0.0.0.0:8000`.
