      How does your DNS Lookup API work?

      We provide a DNS lookup RESTful API, which was developed explicitly for server-to-server communication. When a DNS lookup is performed, your system and the WhoisXML API network communicate with each other using the HyperText Transfer Protocol (HTTP) or HTTP Secure (HTTPS) protocol. We then deliver the results in JavaScript Object Notation (JSON) or Extensible Markup Language (XML) format.
