WHOIS Lookup API

You can fetch WHOIS record of any domain name through:

https://api.whoxy.com/?key=xxxxx&whois=example.com

WHOIS API digs into WHOIS registry referral chains until the correct WHOIS servers are found, for the most complete WHOIS data.
Our WHOIS parser converts WHOIS data into well-structured fields (XML & JSON), which can easily be read by your application.
WHOIS API supports a total of 2026 Domain Extensions (gTLDs, ccTLDs & new gTLDs), ensuring all domains are supported.

Retrieving Data in XML Format

Simple add "&format=xml" to any of your API calls and get results in XML Format.

https://api.whoxy.com/?key=xxxxx&whois=example.com&format=xml

Kindly use XML format only if your application strictly requires XML data. Compared to lightweight JSON format, XML carries a lot of extra baggage. This results in slower data transmission, and affects the overall performance of your application interacting with our API. We highly recommend you use JSON format whenever possible.
