Errors and production

Retry rules, idempotency, and the minimum production checklist.

400 / 422

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

The account balance is insufficient.

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

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.
