Rate limits & fair use
No daily or monthly caps. Just fair-use burst limits to keep the API fast for everyone, and how to raise yours.
There are no daily caps and no monthly caps. FFraud is free at scale on purpose. The only limit is a fair-use burst limit that keeps responses sub-millisecond for everyone.
| Endpoint class | Burst limit |
|---|---|
Public (/public/*), per IP | Hundreds of requests per second |
Authenticated (/v1/*), per key | Hundreds of requests per second |
Cross the burst limit and you get a 429 for a moment, not a paywall. It clears on its own. Almost no real pipeline hits it.
Running something heavy (a large batch backfill, a high-QPS gateway)? Email team@ffraud.com with one sentence about what you are building and we raise your limit. Still free.

- Cache responses. Our edge keeps an anonymous IP lookup (
/public/ip/<address>) for up to 24 hours and the other public answers for 5 minutes; calls with an API key skip that cache and get a fresh answer. You can cache longer on your side. - Use
/v1/ip/batch(up to 100) instead of 100 single calls. - For a whole blocklist, download the open data once a day instead of calling per-IP.
