Limits and timeouts

Time to first byte and stream idle timeouts differ from the route maximum of 15 minutes. Clients, proxies or providers may end requests earlier; this is not a promise of 15 minutes for every request.

HTTP 429 can mean local admission pressure, a full queue or upstream throttling. Read the error and Retry-After; it does not imply unlimited RPM or TPM.

Honor Retry-After and use bounded exponential backoff with jitter. Cap attempts and total time. For video jobs that may already exist, look up the job ID before submitting again.

Examples receive source review and local checks; this does not establish compatibility with every app version. Check settings, send a small request and confirm usage before production use.
