API Rate Limiting Tuning overview

Tunes API rate-limiting configurations to balance abuse prevention with legitimate traffic needs -- analyzing request-rate distributions across API consumers to identify percentile thresholds, reviewing 429-response incidence and correlating with customer-impact tickets, evaluating burst-allowance and sliding-window parameters against traffic-spike patterns, load-testing proposed rate-limit changes in staging with synthetic client profiles, configuring per-endpoint and per-tier differentiated limits, updating rate-limit response headers and developer documentation, and monitoring post-deployment metrics for false-positive throttling. Produces rate-limit configuration change record and impact analysis. Excludes API architecture redesign.
