FAQ

Are there free Test Data APIs without an API key?

Yes. 31 free Test Data APIs need no API key or sign-up, including AddressMock API, DummyJSON API and flaky API. You can send a request straight away.

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

13 of them also support CORS, including AddressMock API, DummyJSON API and flaky 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.
