Total balances from API

I am searching the best way to find total balance from Binance account.
After reading documentation and this forum I found “GET /sapi/v1/accountSnapshot (HMAC SHA256)” This is ok for SPOT MARGIN and FUTURES.
But about total balance i need balance to earn. Does one know how I can do that ?

And if not exist this info from API how i can make a request from binance to do this kind earn API a possibility in the future?
or how can i make a request to Binance API team to know roadmap that maybe or not have “API earn”?

what is this?

Hi Dino , thanks for your response. I need balance from tab earn to complete total balance.
