Tokios exposes standard OpenAI and Anthropic API surfaces, so any tool or library that allows you to override the base URL works out of the box. The only changes needed are the base URL and your Tokios API key.

If your client uses OPENAI_BASE_URL or ANTHROPIC_BASE_URL, you can set those environment variables once and every compatible tool in your terminal session picks them up automatically.
