The Whois API returns well-parsed WHOIS fields in XML and JSON formats. The service covers over 7.0B WHOIS records, with close to 600M domains and 2,900 TLDs tracked. The API allows developers to monitor domain registrations, check domain name availability, and learn more about domain registrants to avoid fraudulent and criminal activities. The API can also be used for brand protection and other purposes.
How does it work? The service automatically follows the WHOIS registry referral chains until it finds the correct WHOIS registrars with the most comprehensive WHOIS data.
