How to call it

Send the official Responses document to the base URL above with your organization key and this exact model id. Streaming arrives as ordered events with one terminal event.

  • Retries: send an Idempotency-Key and a retry replays the original response instead of billing twice.
  • Errors: typed envelopes tell you whether to retry, wait, or fix the request.
  • Keys: mint and revoke organization keys from the console.
