Binance API, how to read total balance value in BTC (or USD), or how to read earn wallet details

Using Binance API, I want to get my total account balance in BTC (or USD)

I am able to get the spot wallet balance by querying /api/v3/account endpoint.

In my case, the total balance is the SUM of spot wallet + earn wallet.

const totalBalance = spot + earn

With only spot, I am not able to calculate totalBalance nor earn.

Using the Binance API, how can I get the totalBalance or earn?
