IPASIS

IPASIS provides real-time bot detection and fraud prevention through a simple REST API. It analyzes IP addresses and email addresses simultaneously, returning an Interaction Trust Score (0-100) that indicates whether an interaction is from a legitimate user, a bot, or a fraudster.

Key capabilities include VPN/proxy/Tor detection (including residential proxies), IP reputation scoring, email validation and risk assessment, and device fingerprint correlation. All delivered in a single API call with sub-20ms response times.

IPASIS is built for developers who need to protect signups, logins, payments, and API endpoints from automated abuse. The free tier includes 100 requests/day with no credit card required.
