Get domain registration data and ownership information
GET /v1/whois?domain=example.com
WHOIS is a protocol for querying databases that store registered domain name information. It reveals the domain registrant, registration and expiration dates, nameservers, and registrar details.
Many domain registrars offer WHOIS privacy protection that masks personal information. GDPR and other privacy regulations have also led to redacted WHOIS data for domains registered by individuals.
RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It provides structured JSON responses, better internationalization support, and more consistent data formats across registrars.
