FAQ

What providers are supported?

See [the providers](./src/main.ts#L17) for the implementation.

undefined

Set a custom OpenAI endpoint with `OPENAI_API_URL` to use OpenRouter

`ANTHROPIC_MODEL` and `ANTHROPIC_SMALL_MODEL` are supported with the `/` syntax.

How does this work?

Claude Code has added support for customizing the Anthropic endpoint with `ANTHROPIC_BASE_URL`.

anyclaude spawns a simple HTTP server that translates between Anthropic's format and the [AI SDK](https://github.com/vercel/ai) format, enabling support for any [AI SDK](https://github.com/vercel/ai) provider (e.g., Google, OpenAI, etc.)
