WhoisXML API WHOIS History API review
A focused API for retrieving historical WHOIS records with flexible query and output options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
WhoisXML API WHOIS History API provides programmatic access to historical WHOIS records for domains. It is suited to cybersecurity research, fraud prevention, digital marketing, domain investigations, and commercial applications that need historical registration information through an API. The service supports GET and POST requests, API-key and authentication-token access, and JSON or XML responses. Its focus is narrow and clear: historical WHOIS retrieval rather than a broader domain-management workspace.
The retrieval workflow separates preview from full access. Preview mode returns available record counts and costs 1 DRS credit, while full historical record purchase mode costs 50 DRS credits. Date-based filters can target detected, created, updated, and expired domains, and an option can suppress live-WHOIS queries. These controls make the API suitable for applications that need to check record availability before requesting complete historical data. The published access options include Free access with 500 DRS credits, followed by one-time bundles of 1,000, 5,000, 10,000, 20,000, 30,000, 50,000, and 100,000 DRS credits. The stated starting price is 19.
This product is a strong fit for teams that already work with APIs and need historical WHOIS data in structured formats. The free access option provides an entry point, but its stated 20-request monthly limit may constrain recurring workflows, while full-record requests consume credits considerably faster than previews. Buyers should choose it when historical retrieval, date filtering, authentication, and JSON or XML output are central requirements. Those seeking a standalone interface or a general-purpose domain tool should consider a different type of product.
