How can I use the API to get my Apex Stats in real time?

I want to get the all time stats in a separate window and then I want to use it and subtract the value of the last match from the current match to see my Current game damage stats. Is there already something like it out there maybe?

Hey @RoyaleNite, and welcome to our community.
First, sorry for the late response!
For your question: You can find all the supported Apex events here.
And the Apex events sample app here. (note that all the sample apps, are in the same directory).

I’m not that I completely understand what you are aiming for, but we don’t have anything like out of the box. It would be best if you implemented it with our infrastructure.
