Global Public API 'Status Code Error Rate' Drift
The page measures two figures: the median error rate (%) across a broad set of public APIs, and the number of those APIs whose error rate exceeds 10%. Data are gathered by continuously polling a curated list of publicly accessible endpoints, recording each HTTP response, and calculating the proportion of non‑2xx status codes for every API. These per‑API error rates are then aggregated to produce the median and the high‑error count.
Monitoring these metrics provides a transparent, global view of the reliability of the web’s data layer. By exposing how often public APIs return error codes, it highlights systemic stability issues that might otherwise remain hidden behind internal monitoring alone.
