Authentication
Every model request must carry a Bearer token in the Authorization header. Relay stores only the SHA-256 hash of your API key.
Streaming
Set stream: true to get a standard SSE data stream. Credit deduction completes automatically once the stream ends.
Response format
Non-streaming responses use a standard JSON response format, plus a Relay request ID in the response header for easy log lookup.
