Laufender Saldo in API

Hello everybody!

I am developing a small application that would get several information from Papershift. Now I need to get the current time saldo (Laufender Saldo) of each employee through the API. Is this value possible to get through the Time Tracking, Metrics or any other function in the API? A small example code would be very appreciated.

Thanks a lot for your help and have a nice day!
