Why use RDAP instead of WHOIS?
RDAP provides standardized, machine-readable JSON responses, supports HTTPS encryption, handles international domain names better, and is the ICANN-mandated replacement for WHOIS.
What TLDs are supported?
Most major TLDs including .com, .net, .org, .io, .dev, .app, .co, .me, and many country-code TLDs. Support depends on the registry providing an RDAP endpoint.
