Parsed whois API with JSON output, at your service.

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.
