For the past 5 years we have been improving our whois API. We parse the whois data and deliver it to you in a JSON output. This is the list of TLDs (top level domains, domain extensions) we support. Here is our very simple documentation that hasn't changed over the years, we like the reliability of a consistent API documentation. As one of your first steps, we recommend you look at some of our code examples.
This website, administration and our API are on https protocol and you can whitelist the IP from which you are accessing your API key.
Compared to other whois APIs on the market, we are more affordable and provide more value for the same money.
Build your ideas faster with WhoAPI, and we would love to highlight them on our blog, newsletter and social media pages.
