title: API to list top level domains
body: <p>Anyone recommend any good web service to query and list all possible TLDs. </p>
  
  <p>I'm currently looking at <a href="http://domainapi.com/" rel="noreferrer">http://domainapi.com/</a> right now. I can query TLDs, but I cant find a way to list them. If anyone can think of any other good examples that have updated TLDs.</p>
