IPASIS Bot Detection and Fraud Prevention API is a REST API service that provides IP address reputation lookups and email address validation with combined risk scoring. The API exposes two endpoints accessible via a single API key: IP Lookup (/v1/lookup): - Returns geolocation data (city, region, country, coordinates, postal code, timezone) - Provides ASN details including ASN number, owner name, BGP route, and type - Identifies company information associated with the IP range - Detects privacy/anonymization services: VPN, proxy, Tor exit nodes, iCloud Private Relay, hosting/datacenter IPs, AI provider IPs, and known crawlers - Flags IPs reported for abuse - Returns abuse contact information - Lists domains hosted on the IP Email Validation (/v1/validate-email): - Validates email syntax against RFC standards - Checks deliverability via MX record lookup, catch-all detection, and SMTP connection testing - Classifies email type as personal, disposable, role-based, or business - Detects disposable/temporary email domains (120,000+ domains tracked) - Identifies gibberish or bot-generated usernames using entropy and pattern analysis - Flags newborn domains (registered less than 14 days ago) - Reports domain age in days Combined Risk Scoring: - Produces a numeric risk score from 0 to 100 combining email and IP signals - Assigns risk levels: LOW, MEDIUM, HIGH, CRITICAL - Provides a recommended action: ALLOW, REVIEW, or BLOCK - Lists primary reason codes contributing to the score (e.g., email_disposable, ip_is_tor) The API supports requests via cURL, JavaScript (fetch), Python (requests), Go (net/http), and Java (HttpClient). Authentication is handled via an API key passed as a header or query parameter.
