Query any domain's registration data using RDAP (Registration Data Access Protocol), the modern structured replacement for WHOIS. Returns registrar, registrant, nameservers, creation/expiry dates, and domain status flags — all parsed from JSON.

Supports .com, .net, .org, .io, .dev, .app, .co, .uk, .de, .nl, .fr, .eu, .ca, .au, .jp, .ai, .me, .info and more via direct registry RDAP endpoints. Flags domains expiring within 30 days. Raw RDAP response available for inspection.

About RDAP

RDAP (Registration Data Access Protocol) is the modern replacement for WHOIS. It returns structured JSON data directly from the domain registry, with consistent formatting and proper encoding. TLDs without RDAP support may return limited data.
