API reference

Handle retries without starting duplicate agent work.

Every initial runtime request should include an idempotency key. Reuse it only when retrying the exact same request.

Idempotency

  • Generate a fresh UUID for each new runtime task.
  • Reuse the same key only for transport retries of that same request.
  • If a stream drops after response.created, recover from the session instead of sending a new task.

HTTP errors

Errors are JSON responses shaped like { "detail": "..." } with standard HTTP codes. Common cases include 400 for invalid body, 401 for bad or missing key, and 404 for missing or inaccessible resources.
