Our verdict on WhoAPI
WhoAPI provides hosted APIs for retrieving parsed WHOIS records and related domain data. It is designed for developers, freelancers, businesses, cybersecurity teams, registrars, hosting companies, and other organizations that need structured domain information. Responses are available in JSON and XML across more than 1,500 top-level domains, with REST access through HTTP or HTTPS GET requests. A browser-based console supports manual single WHOIS checks, while separate APIs cover domain availability and scoring.
The published plans show a Freelancer tier at $52 per month with top gTLDs and ccTLDs, JSON and XML output, cached Whois, a manual-check console, and email support. Business is priced at $499 per month and adds live WHOIS access, additional TLDs pending availability, and priority support. Enterprise includes the same core output and live WHOIS capabilities with VIP support. A one-time 10,000-request welcome allowance is described separately from the paid plans, while monthly quotas are part of the service model. The product details also identify 40,000 monthly requests from $52.
WhoAPI fits teams that want parsed records instead of handling varied WHOIS responses directly. Integrations and SDK coverage include Python, JavaScript, PHP, Ruby, Java, Objective-C, and C#/.NET, alongside IP allowlisting for API requests. Cached results suit repeat lookups, while eligible higher tiers provide live requests when fresher data is needed. The main trade-off is workflow scope: bulk use may require building a checker around the API rather than relying on native multi-domain submission. Choose WhoAPI for programmatic, structured WHOIS coverage and availability checks; choose an alternative if a recurring free plan or built-in bulk submission is central to the workflow.
