Reasons to use a WHOIS lookup API...
Check a domain name's availability
If you want to know the availability of a domain name, use our WHOIS lookup API and we'll let you know if the domain is available, or not.
Learn when a domain will expire
If you want to buy a domain, knowing when it expires is helpful. As the date approaches the owner may want to sell, or better yet, let it expire — and you're right there to scoop it up.
Find a domain owner
Whether you want to buy a domain or learn who owns it, use our WHOIS lookup API. Enter the domain name and you'll get key info, including availability, ownership, creation, and expiration.
What is WHOIS (Domain Name Lookup)?
WHOIS is a database that consists of mandatory information about a registered domain, or more precisely, the registered users of an Internet resource. A WHOIS information lookup is how we can find a wider range of information on a domain name, an IP address block and the domain availability status. ICANN maintains the database and updates it regularly to help prevent fraud and identity theft.
