IPASIS

About IPASIS

IPASIS is an API for bot detection and fraud prevention that evaluates risk based on email addresses and IP intelligence. Its primary endpoint, GET /v1/validate-email, accepts an email address and an optional IP, returning a risk score from 0 to 100 along with a risk level (LOW, MEDIUM, HIGH, CRITICAL) and a recommendation (ALLOW, REVIEW, BLOCK). The score is derived from signals such as disposable email domains, newly registered domains, gibberish or bot-generated usernames, role-based accounts, and IP-based factors including Tor exit nodes, proxies, VPNs, hosting/datacenter IPs, and reported abuse. Email responses also include syntax validity, deliverability status, domain age, MX record presence, catch-all status, and SMTP connection results.

A separate GET /v1/lookup endpoint accepts an IP address and returns geolocation data (city, region, country, coordinates, postal code, timezone), ASN information (number, name, route, type, domain), and the associated company name for the IP range.

Requests are authenticated via an X-API-Key header or query parameter. A free API key is available offering 1,000 requests per day without a credit card. Client examples are provided for cURL, JavaScript (fetch), Python (requests), Go (net/http), and Java (HttpClient).
