IPASIS

About IPASIS

IPASIS is an API for bot detection and fraud prevention that combines IP intelligence and email validation into a single risk verdict. It assigns each interaction a 0-100 trust score based on signals such as VPN/proxy usage, datacenter or hosting IPs, disposable or role-based email addresses, newly registered domains, Tor exit nodes, and gibberish usernames, classifying results as trusted (0-39), suspicious (40-79), or bot/fraud risk (80-100). The service reports sub-20ms response times (around 20-30ms at p95) and is deployed across three global regions (US, EU, Asia).

Risk data is drawn from multiple threat feeds, including RIPEstat, MISP Threat Intel, X4BNet, DNS monitors, Certificate Transparency harvesting, GeoLite2, RDAP/Whois, WhoisDS, and community disposable-email lists, with each risk score accompanied by the specific reasons behind it. The company states it tracks over 120,000 disposable email domains and monitors over 210,000 newborn domains, with feeds updated sub-hourly.

The product targets developers and businesses looking to prevent fake signups, bot-driven logins, fraudulent leads, affiliate fraud, coupon abuse, and risky checkout transactions. It offers a free tier of 100 requests per day with no credit card required, and states integration is possible in about 2 minutes in any language. It is described as TLS-encrypted, GDPR compliant with no PII stored or logged, offers 99.99% uptime, and has a DPA available for enterprise customers.
