What these figures do not show

A passing check means the API's server answered one plain request from us, with no key and no redirects followed (web-reach/2): a response a live API gives without credentials (2xx, a redirect, 400, 401, 403, 405, 406, 415, 422 or 429). It does not show that its operations work, what they cost, or what a key gives access to.
Listed in APIs.guru, a collection of OpenAPI descriptions; the address, the categories and the security schemes come from its description of the API, as stated there. The description itself is not republished.
Limited evidence: monitored for 2 days (less than 30).
