OpenAI-compatible proxy for [Claude.ai](https://claude.ai) Web API.

Converts standard `/v1/chat/completions` requests to Claude.ai internal API. Works via cookie-based auth — no API key needed.

**Use cases**: local development, testing, automation, integrating Claude.ai into OpenAI-compatible tools

## Features

- OpenAI-compatible `/v1/chat/completions`
- Streaming (SSE) and non-streaming
- Model: `claude-3-5-sonnet`, `claude-3-5-haiku`, etc. (matches Claude.ai models)
- Automatic TLS retry with exponential backoff
- Rate-limit handling (429, daily reset)
- CORS enabled

## Requirements

- **Python 3.10+**
- `pip install -r requirements.txt` (uses `curl_cffi` with Chrome impersonation)
- **Firefox** with [cookies.txt](https://addons.mozilla.org/en-US/firefox/addon/cookies-txt/) extension
- **VPN/proxy** — Claude.ai blocks non-residential IPs (Cloudflare)
