How this is measured
Every API in our catalog is checked hourly by an HTTP HEAD request to its base endpoint from our own monitor — not pulled from a provider's status page or marketing claims. "Uptime %" is the share of checks in the trailing 7 days that returned a non-error response; "avg response" is the mean latency of successful checks in that window. Rankings update automatically as new checks come in. Read more in our About page.
