Our verdict on WhoisXML API WHOIS History Search
WhoisXML API WHOIS History Search is a web-based tool for investigating how domain records change over time. It is designed for cybersecurity research, fraud investigation, domain due diligence, brand protection, and market research. Users can search historical WHOIS records, review ownership timelines, examine registrar and registration changes, and inspect historical nameserver and contact details. The tool fits researchers who need more than a current domain snapshot and want to trace changes across a domain's recorded history.
Pricing uses DRS credits through a freemium model. The free plan includes 500 DRS credits, equivalent to 10 WHOIS History API calls. Paid tiers include 1,000 credits with 20 API calls equivalent; 5,000 with 100; 10,000 with 200; 20,000 with 400; 30,000 with 600; 50,000 with 1,000; and 100,000 with 2,000. The credit model can support occasional investigation through the free allowance or larger research workloads through higher tiers. Credits may apply across DRS web tools and APIs, so teams should consider how their wider Domain Research Suite activity affects consumption.
Its strongest capability is the combination of historical record access and comparison. Researchers can compare historical WHOIS records, identify changed fields, pivot into related DRS searches, and download historical records as PDF files. Integration with the WhoisXML API WHOIS History API extends the same historical data into programmatic workflows, while the web dashboard suits browser-based research. Choose it when ownership changes, registration history, and record comparisons are central to the investigation. Choose another tool when the primary requirement is a broader standalone domain workflow rather than historical WHOIS analysis.
