That is the whole page.

FFraud is a free, open anti-fraud project, not a sales funnel. The API has no caps, the database is MIT licensed on GitHub, and there is nothing to upgrade to.

The one footnote: fair-use rate limiting

There are no daily or monthly caps. To keep responses fast for everyone, bursts are rate limited per key, at a level almost no real pipeline reaches. If you run something heavier, email us one sentence about what you are building and we raise it. Still free.

Your server asks. We answer.

Every signup, login and checkout is one lookup away from knowing whether to trust it.

Could be a real customer hiding their IP. Ask for a second factor instead of blocking.

Why is this free?

There is none. FFraud is an anti-fraud project, not a sales funnel. Fraud data gets better the more people use it and report to it, so a paywall would make it worse.

There is no daily or monthly cap. Bursts are rate limited to keep the API fast for everyone: go over and you get a 429 for a moment, not a bill. Need steady heavy traffic? Email us and we raise it, still free.

IP reputation with threat categories such as command and control, botnet, brute force and phishing, plus location, VPN, proxy and Tor classification, ASN and datacenter detection. The open database lists 1,476,708 confirmed abusive IPs and 222,780 disposable email domains. Every listed IP is confirmed by our honeypot sensors and community reports before it is published.

Yes, the API and the open data. The data is MIT licensed, so you can use it in commercial products, redistribute it and build on it. Attribution is welcome, never required.

Not for anything that is free today. If paid features ever exist, they will be extras such as custom datasets or dedicated infrastructure, never limits on what is free now.
