# AI API Rate Limit Debugging: Safe Retries and Evidence

A slow or failed API request is not always a rate-limit issue. Capture a redacted response and trace how the client retries. Use AI to locate the relevant code path and propose bounded handling that respects the provider’s documented limits and the operation’s side effects.

## Your brief

1. Provide status code, redacted response body, request timing and safe correlation IDs. Remove API keys, authorization headers and private payloads.

   ____________________

2. Identify the provider’s current limit documentation, account quota and any Retry-After header. Separate concurrent-request limits from token, request or billing limits.

   ____________________

3. Supply the retry code and explain whether the operation creates a billable job or changes state. Identify available idempotency support and cancellation behavior.

   ____________________

## Prompt

Analyze [redacted response, docs and retry code]. Classify the error from evidence, trace retry behavior and propose a bounded fix. Respect Retry-After and documented quotas. Distinguish retryable errors from auth or billing failures. Prevent duplicate side-effecting jobs using supported idempotency. Report tests actually run and list unknown account/provider state. Do not bypass limits or expose secrets.

## Illustrative example

Illustrative sequence: a request receives 429, then the client immediately sends three more requests. The fix considers the documented wait, bounded backoff and a visible recoverable state. If the first call may already have created a media job, the code checks supported job or idempotency semantics before retrying. A 402 billing error is not fixed by exponential backoff.

## Acceptance checks

- [ ] Is error classification based on actual status and provider documentation rather than a generic message?
- [ ] Are retries bounded, cancellable where relevant and safe for billable or state-changing operations?
- [ ] Are account limits, code verification and live provider behavior kept distinct in the report?

Do not rotate accounts or credentials to evade a quota. Respect service limits, reduce unnecessary calls and show a useful retry state. Retry code cannot solve a provider billing rejection.
