Which protocol endpoints are supported?

Public endpoints cover Claude Messages, OpenAI Responses, Chat Completions, Embeddings, Models, Usage, and Gemini v1beta.

Steps

1. Choose one protocol for the client instead of mixing request bodies.
2. Copy the endpoint and authentication header from its guide.
3. Verify a non-streaming request before enabling streaming or WebSocket.

Limits and exceptions

Protocol compatibility does not mean every upstream parameter is fully implemented; models and actions depend on the console and public documentation.
