Anthropic-compatible clients

Use the Anthropic client with base_url="https://api.zrelay.net" and your key. The SDK adds /v1/messages. See Messages examples.

Validate the route

Pin and follow your framework’s installed version. Test one small request, then streaming and tools independently. A client that defaults to Responses needs a Responses route; Chat Completions compatibility does not automatically cover it.
