Argus is a lead verification and fraud detection platform that evaluates 101 data points across 7 verification layers — including behavioral biometrics, device fingerprinting, email/phone validation, geographic cross-referencing, and bot detection — to deliver a single trust score in under 150 milliseconds. Unlike siloed tools that check one signal at a time (email checkers, phone validators, IP lookup), Argus cross-validates every signal against every other signal, catching compound fraud patterns that no combination of separate tools can detect. One SDK. One API call. One verdict. Free tier includes 50 verifications/month at full depth with no credit card required.
