Real-Time Fraud Defense in Three Simple Moves

We handle all the verifications so you can focus on building—no wasted resources, no fake users reaching your database.

Send three tiny signals

Pass any combination of email, IP address, and user-agent with each sign-up request using a REST call — no external libraries, no SDKs, no extra form fields.

We run 20+ layered checks in ≤ 500 ms

We verify email syntax, domain age, MX records, disposable inboxes, IP geo/ASN, TOR or datacenter routes, headless user-agents, automation fingerprints, and many more correlations to flag risky traffic before it provisions resources.

Fraud Score & flags

We roll every test into a single Fraud Score (0 – 100) and return a clear list of triggered rules so your app can auto-accept, review, or block.
