Every endpoint, and how it is actually doing

Success rate is the share of requests that returned data, over the last 30 days, excluding requests that failed because of the parameters you sent. A 404 for a profile that genuinely does not exist is a success: we answered the question correctly.

Latency is measured at our edge, from the request arriving to the response leaving, and excludes cache hits — which would flatter it considerably.

Whose calls. Customers’ calls only: the no-key demo and our own testing are left out. An endpoint shows a number once it has 50 calls in the last 30 days.

Operational means at least one source is healthy and serving. Where we can, a surface is served by more than one, so a problem at one of them is invisible to you; the response shape does not change either way.

Degraded means some endpoints on a surface are failing over or slow. Unavailable means we cannot serve that endpoint at all — and calls to it are not charged.
