Errors and production

Retry rules, idempotency, and the minimum production checklist.

400 / 422

Fix the request fields or unsupported option; do not retry unchanged.

401

Check that the API key is present, active, and sent as a Bearer token.

402

The account balance is insufficient.

409

The Idempotency-Key is processing or was reused with another body.

429

Back off according to Retry-After before retrying.

5xx

Retry with exponential backoff and keep the original Idempotency-Key.

  • Keep API keys on your server for public mobile and browser applications.
  • Set a unique Idempotency-Key for every billable async operation.
  • Persist task_id so polling can resume after a restart.
  • Use a timeout for every HTTP request and surface the request ID in support reports.
  • Read live model metadata instead of hard-coding prices and supported options.
