How To Use Whois API

Whois API

How can Whois API help you?

Do you need an API that does Whois lookups programmatically? With a Whois lookup API, you can check millions of domain names if they are registered or not. If the Whois API returns a positive result, then you can check domain expiration dates, domain registration dates, nameservers, which domain registrar holds the domain name and other information.

With this whois information, you can do analytical batch lookups around domain names.

In this article, we listed different use cases for a Whois lookup API.

But in the meantime, try our robust whois API with live whois, which we are improving every month!
