Web API latency tracking

API Latency Baseline Audit

Establish how your web APIs actually respond under real traffic—p50, p95, and the routes that quietly stretch every release.

Product and platform teams often argue about “slow APIs” with different charts and different windows. The baseline audit rebuilds a shared picture from the traces, logs, and synthetic checks you already have—plus the gaps that leave overnight spikes invisible.

We inventory public and internal web API routes that matter to user journeys, sample latency distributions across environments, and mark which endpoints dominate tail latency when traffic is ordinary rather than peak theatre.

You leave with a route-level latency map, a shortlist of measurement gaps, and a brief your engineering and product leads can both defend in the same meeting.

Typically included

  • Route-level latency inventory
  • p50 / p95 / p99 snapshot notes
  • Measurement gap list
  • Shared engineering–product brief
