Use this when the user asks who owns a domain, when it expires, which registrar or nameservers it has, whether it is registered, or whether a transfer or delete lock is set — the WHOIS question. Read a domain's registration from the registry over RDAP: registrar (with IANA id), registration/last-changed/expiry dates, EPP status codes verbatim, nameservers, whether the delegation is DNSSEC-signed, and an abuse contact where one is published — `redacted: true` is the post-GDPR norm, not a failure. Observation only: no record is composed, and `pendingDelete` or a near expiry is something to REPORT, never advice to buy. `status` is registered | not_registered | unknown, and `unknown` is NOT absence — the registry did not answer, and `reason` says whether that was a rate limit, a timeout, a registry error, or a TLD with no RDAP service. Never tell anyone a name is free unless `status` is exactly not_registered.
