FAQ

Are there free Social APIs without an API key?

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

5 of them also support CORS, including 4chan API, Lanyard API and SwarmMemo 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.
