Stop worrying about what your AI agents spend. One API call tells you if a purchase is safe, risky, or fraud — before the money moves. Built for production, ready in minutes.
Send transaction details to POST /v1/evaluate. Get back a decision, risk score, factor breakdown, and compliance status. That's it.

}A single score from 0 to 100 tells you how risky each purchase is. We look at amount, merchant, spending patterns and more — so you don't have to.
European payment rules (PSD2/SCA) are built in. We flag when extra authentication is needed and when it isn't — you stay compliant without reading regulations.
Decisions come back in under 50 milliseconds — faster than a blink. Your users never wait, and your agents keep working at full speed.
Every decision comes with a clear explanation and a searchable history. When something goes wrong — or when auditors ask — you have all the answers.
Set spending limits, block categories, or adjust how strict the system is. Every team gets its own private setup — no surprises, no shared data.
Drop our SDK into your app and you're protected. Works with Python, Node.js, and the browser — or call our API directly from any language.
