# anthropic-proxy
A proxy server that transforms Anthropic API requests to OpenAI format and sends it to openrouter.ai. This enables you to use Anthropic's API format while connecting to OpenAI-compatible endpoints.
## Usage
With this command, you can start the proxy server with your OpenRouter API key on port 3000:
```bash
OPENROUTER_API_KEY=your-api-key npx anthropic-proxy
```
Environment variables:
- `OPENROUTER_API_KEY`: Your OpenRouter API key
- `PORT`: The port the proxy server should listen on (default: 3000)
- `REASONING_MODEL`: The reasoning model to use (default: `google/gemini-2.0-pro-exp-02-05:free`)
- `COMPLETION_MODEL`: The completion model to use (default: `google/gemini-2.0-pro-exp-02-05:free`)
- `DEBUG`: Set to `1` to enable debug logging
## Claude Code
To use the proxy server as a backend for Claude Code, you have to set the `ANTHROPIC_BASE_URL` to the URL of the proxy server:
```bash
ANTHROPIC_BASE_URL=http://0.0.0.0:3000 claude
```
