IP2Location.io IP2WHOIS review
A broad-TLD WHOIS API with a free tier and paid automation options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IP2Location.io IP2WHOIS is a hosted domain intelligence API for developers, security teams, fraud investigators, infrastructure analysts, and organizations building domain intelligence workflows. It looks up WHOIS records by domain name and can return creation, update, and expiration dates, domain age, registrar information, nameservers, and registrant, administrative, and technical contact fields where available. Requests use bearer-token or URL-parameter API-key authentication, with responses available in JSON or XML.
The pricing structure gives smaller integrations a clear starting point. The Free plan costs $0 per month, includes domain WHOIS API access and standard support, requires attribution, and provides 5,000 monthly lookups. A seven-day trial is available. Starter costs $49 per month and adds priority support, overage queries, and bulk query. Plus costs $249 per month with the same listed additions, while Security costs $499 per month and also includes a full-access trial. This makes the free tier suitable for limited development or lower-volume workflows, while paid plans are aimed at applications needing more query capacity and support.
Its main strength is breadth across domain registries combined with a practical integration ecosystem. IP2WHOIS supports 1,221 TLDs and 634 ccTLDs, and connects with Zapier, Make, Pipedream, Pabbly, Integrately, Quickwork, ViaSocket, OttoKit, Maltego, Splunk SOAR, and Steampipe. That combination fits automated enrichment, investigation, and security workflows that already operate through APIs or automation platforms. Choose it when broad TLD coverage and structured WHOIS fields matter more than a graphical product experience. Teams seeking a standalone interface rather than an API-centered service should consider a different type of tool.
