Checks whether a domain is registered and returns registrar, registration date, expiry date, days_until_expiry, and current EPP status flags.

Checks whether a domain is registered and returns registrar, registration date, expiry date, days_until_expiry, and current EPP status flags. Works for any TLD that supports RDAP (effectively all gTLDs and most ccTLDs). Backed by rdap.org, the public RFC-7480-compliant aggregator; 404s map to is_registered: false rather than an error. Use it as an RDAP lookup, WHOIS replacement, domain registration checker, or expiry date lookup.
