Our verdict on WhoisFreaks WHOIS API
WhoisFreaks WHOIS API provides structured domain-registration data for developers, cybersecurity teams, threat intelligence workflows, researchers, brand protection, due diligence, and domain portfolio analysis. Its API returns registrar, registrant, registration and expiry dates, nameservers, status codes, and raw WHOIS data in JSON or XML. Queries can use live WHOIS servers and RDAP sources, while historical records, ownership timelines, and reverse searches add investigative depth beyond a single current lookup.
The product is designed for high-volume processing. API requests can include up to 100 domains, and bulk file processing supports lists of up to 3 million domains. The published capabilities also include JSON, XML, and CSV export formats, plus fields covering registrar, registrant, contacts, dates, nameservers, and status. Official SDKs are available for Python, JavaScript, TypeScript, Java, Kotlin, C# / .NET, Ruby, Go, and Swift. Integrations include MS Security Copilot, Make, MISP, MCP Server, Postman Collection, and n8n, giving teams several ways to connect WHOIS data with security and automation workflows.
Pricing is structured around API usage rather than an unlimited free tier. API Credits cost $150 one-time for 50,000 credits, with lifetime credits that do not expire. The Yearly Subscription costs $63 per month billed annually and includes 50,000 API credits per month plus unlimited surcharge credits. The Monthly Subscription costs $75 per month and includes the same credit and surcharge structure. Signup credits are limited to 500 credits. WhoisFreaks is a strong fit for teams that need historical context, reverse investigation, bulk processing, and broad developer integration; teams seeking a free or primarily manual WHOIS lookup tool should choose a narrower alternative.
