Public API Latency (p50, self-measured)

Median response time of five public data APIs, measured live from the AxioStats refresh runner — self-measured telemetry, not a vendor benchmark.

Executive summary

Public API Latency (p50, self-measured) are led by PyPI Stats p95 at 581 ms (p50 / p95) in the latest week — versus 319 ms (p50 / p95) for runner-up HN Algolia p95.

The strongest growth over the window was FRED graph p50 (+1.1%). Weeks are aggregated Monday-to-Sunday from the public npm API.

Methodology
Three sequential GETs per endpoint with a 10s timeout (fetch + AbortController); the snapshot stores the median per endpoint as a single point. Measured from the refresh runner, so values depend on network and region and are not comparable across runs as an absolute benchmark.
