Programming APIs

Choose an API with clear expectations

Use No Auth to find entries reported as not requiring credentials. It does not mean unlimited use. HTTPS describes source-reported transport support; it is different from the protocol of the documentation link. CORS concerns browser requests, so a service can work on a backend even when browser access is unavailable.

First confirm that the provider still documents your use case. Read its pricing, quotas, data license and privacy terms, then test with non-sensitive sample data in your own environment. Favorites are saved in this browser so you can compare candidates later.
