Whois History API

Whois History API returns all the historical WHOIS records of a domain name that is saved in our local database.
This API call does NOT query the live WHOIS servers, and only returns the records present in our database.
In case Zero WHOIS records are present in our database, you will NOT be charged any API queries.

Retrieving Data in XML Format

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

http://api.whoxy.com/?key=xxxxx&history=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.


Account Balance Check

You can check your account's API query balance through:

http://api.whoxy.com/?key=xxxxx&account=balance
