Troubleshooting

401: check the full key. 400: check parameters, history and context size. 409: inspect the original request. 429: reduce concurrency and respect Retry-After. For uncertain results, check billing before retrying and keep the request ID.

Prepaid, metered billing. Funds are reserved before a call, then settled from upstream usage. An uncertain request may retain its reservation for reconciliation. Third-party software fees are separate.
