Whether you want to build your own free domain discovery platform or just trying to check thousands of domains' availability for any reason, Whois API will help you to do so.
In addition to checking the availability of the domain name, Whois lookup provides registration information of the domain in JSON format, such as the expiration date, registrar, registrant information.
How this API helps
Whois queries are pretty simple to code but when you are dealing with thousands of Whois queries per day it becomes really complicated, since NIC servers have pretty strict rate limits. Our Whois API uses hundreds of Socks5 servers autoscaling itself which does the trick with rotating the IP addresses frequently. We execute millions of Whois queries each day. Our happy customers use this API to discover available domains, discover frauds, build SEO tools, run affiliate sites. They rely on us, and we are addicted to provide the best support that is possible.
