FAQ

Are there free Health APIs without an API key?

Yes. 33 free Health APIs need no API key or sign-up, including FindSaunaPlunge API, Longevity World Cup API and Open Disease API. You can send a request straight away.

Which keyless Health APIs can I call from JavaScript in the browser?

17 of them also support CORS, including FindSaunaPlunge API, Longevity World Cup API and Open Disease API, so a plain fetch from a web page works.

Do APIs without a key have limits?

Usually, yes. Keyless APIs typically rate-limit by IP address, so cache responses and avoid tight loops. For production traffic, an API with a free key tier often gives higher, more predictable limits.
