Frequently asked questions

What is an API rate limit?+

It's the maximum number of requests an API allows in a time window. Exceeding it returns a 429 error, so apps must throttle or back off.

How do I avoid hitting rate limits?+

Cache responses, batch requests, implement exponential back-off on 429s, and check the provider's limit for your tier — listed here for common APIs.

Is the API rate limit database free to use?+

Yes. It is completely free, runs in your browser and needs no sign-up. Any data point you add stays on your device — nothing is uploaded.
