Reliable AI API access: routing, failures and production checks

Account routing and bounded recovery

The gateway selects eligible upstream accounts for the requested group and model. Supported request paths can switch accounts after eligible upstream failures, within bounded retry rules. Capacity, provider quotas and the selected group still matter; switching accounts cannot make an unavailable model available.

Do not treat a discount group and another service group as interchangeable. Check the live catalog and test the exact route you plan to use. If your application needs its own fallback policy, make the decision explicit and preserve the model and request requirements.

Failures you can handle

The integration docs describe authentication failures, insufficient balance, rate limits, concurrency limits and unavailable upstream capacity. Parse the error envelope for the endpoint family you use. Respect Retry-After where returned, bound retries and record request identifiers for support.

Images and videos use asynchronous jobs. Poll to the documented terminal state, inspect failure codes and download the completed output while its temporary URL remains available. Avoid blindly resubmitting a paid job after a network timeout: first reconcile the original task.

A production acceptance checklist

Measure completed-response rate, time to first token, full-response latency and billed cost for the exact model, group, context size and concurrency. Test streaming completion, tool results and media downloads where your product needs them. Keep failed requests in the sample; HTTP 200 or a health endpoint cannot prove usable output.

Start with a small workload and monitor it before increasing traffic. Apixly provides integration documentation and support at [email protected].
