IP2WHOIS API
Data Validation · Development Tools
IP2WHOIS is a domain WHOIS lookup API operated by IP2Location, a well-established geolocation and network intelligence company. Unlike IP geolocation APIs that return information about IP addresses, IP2WHOIS focuses specifically on domain name registration data allowing developers to query who owns a domain, when it was registered, when it expires, and what nameservers it uses.
