Retrieving Data in XML Format

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


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.
