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 [email protected] with one sentence about what you are building and we raise your limit. Still free.
#Be a good citizen
- Cache responses. We edge-cache public lookups for 5 minutes; you can cache longer.
- 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.
