Actually it's not an API but it's works like one.
It parses player data from statistics page on armata.my.games and returns data in python dictionary(it's some kind of JSON).
In order to use this library you need basic knowledge of Python and cookies from armata.my.games(because website just won't give page with statistics if you are not authorized)
You can get library itself at it's github repo: https://github.com/lookandhate/ArmoredWarfareAPI
There are actually instructions how to install and some examples.
For now you can retrieve player stats from all 5 gamemods(including legacy Lords of War mode) and even specify tank if you don't want overall statistics.
