name: WhoisFreaks description: >- WhoisFreaks is a domain and IP intelligence provider whose REST API suite covers live WHOIS, historical WHOIS, bulk and reverse WHOIS, IP and ASN WHOIS, live/historical/reverse DNS, domain availability with suggestions, typosquatting discovery, SSL certificate lookup, subdomain enumeration, IP geolocation, IP reputation and domain reputation. Alongside the live lookup APIs it ships bulk downloadable databases (WHOIS, DNS, subdomains, IP geolocation, IP security, ASN, newly registered domains, expiring and dropped domains, and daily phishing/malware/spam threat feeds), brand/domain/registrant monitoring services with email, Telegram and webhook alerts, ten officially maintained OpenAPI-generated SDKs, a Go CLI, an n8n community node, and an open-source MCP server exposing fourteen domain-intelligence tools to AI assistants. Authentication is a single apiKey query parameter across every endpoint. image: https://whoisfreaks.com/images/logo.png url: https://raw.githubusercontent.com/api-evangelist/whoisfreaks/refs/heads/main/apis.yml created: '2026-07-29' modified: '2026-08-09' specificationVersion: '0.21' tags: - WHOIS - DNS - Domain Intelligence - IP Intelligence / Geolocation - Cybersecurity / Threat Intelligence - OSINT - Reverse Lookup - SSL/Certificate - Domain Monitoring - Brand Protection - Threat Feeds - Domain Availability apis: - name: WhoisFreaks MCP Server description: >- Official open-source Model Context Protocol server (Java) exposing 14 WhoisFreaks domain-intelligence tools to MCP-compatible AI clients.
