Errors and production
Retry rules, idempotency, and the minimum production checklist.
400 / 422Fix the request fields or unsupported option; do not retry unchanged.
401Check that the API key is present, active, and sent as a Bearer token.
402The account balance is insufficient.
409The Idempotency-Key is processing or was reused with another body.
429Back off according to Retry-After before retrying.
5xxRetry 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.
