# Anthropic Messages Proxy

A proxy that transforms Anthropic's `/v1/messages` API format to OpenAI's `/v1/chat/completions` format.

## Usage

Send requests to `/v1/messages` using the Anthropic API format. The proxy will:
1. Transform the request to OpenAI format
2. Forward to HuggingFace's router
3. Transform the response back to Anthropic format

### Example

```bash
curl -X POST https://YOUR_SPACE.hf.space/v1/messages \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $HF_TOKEN" \
  -d '{
    "model": "Qwen/Qwen2.5-72B-Instruct",
    "max_tokens": 1024,
    "messages": [
      {"role": "user", "content": "Hello!"}
    ]
  }'
```

## Features

- Full Anthropic Messages API format support
