FAQ

Are there free Vehicle APIs without an API key?

Yes. 7 free Vehicle APIs need no API key or sign-up, including Bike Reliability API, ProblemsByVin API and TransparentCars API. You can send a request straight away.

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

3 of them also support CORS, including Bike Reliability API, ProblemsByVin API and TransparentCars API, so a plain fetch from a web page works.

Do APIs without a key have limits?
