API operations

Metrics for a small AI API gateway

Track output delivery, billing, and upstream problems with the same request ID.

Separate accepted requests from delivered results

A successful submission only means the job entered the system. Measure successful delivery, elapsed time, and expiration separately.

Join job status, upstream cost, and customer charges by request ID. Check that retries and refunds appear in the same record.

Choose the largest source of failed delivery or support requests, run a controlled change, and compare the same measurement window.
