Domain availability and expiry intelligence via RDAP, the WHOIS successor
Domain availability and expiry intelligence via RDAP, the WHOIS successor. Queries the authoritative registry for any RDAP-enabled TLD: free domains return registered:false, taken ones return registrar, creation and expiry dates, nameservers and EPP status codes. TLDs without RDAP coverage return supported:false. Built for agents that buy, monitor or vet domains.
