IP2WHOIS Information Lookup
IP2WHOIS returns structured WHOIS records - registrar, creation/update/expiration dates, name servers, and computed domain age - for any domain name, part of the IP2Location.io API family. It's fully key-gated with no CORS header on its responses (confirmed via a live 401), so it's meant for server-side calls; the shared IP2Location.io free plan includes 500 WHOIS lookups a month before paid tiers start at $49/month.
