API testing · Server-side speed

Quick check — one round-trip, precise timing

Fire a single HTTP request from the GhostAPI server. You get DevRoutes-style phases: total time, time-to-headers (TTFB), and download. HTTP 4xx/5xx still include timings; only user timeouts and true transport failures surface as errors.

  • Single shot
  • TTFB vs download bars
  • Server-side clock

Clock runs on GhostAPI infrastructure (not in your browser).

Timings include server egress + target API; for CI-grade load, use dedicated runners (e.g. k6).

Public URLs only — same safety rules as the rest of API testing.

Configure the request on the left, then run a quick check — TTFB, download, and total land in this panel, aligned with the form.
