Get balance for specific coin on spot wallet account with javascript or postman

Greeting to all. Thanx in advance for your time.
I am trying to get/save the current value of a particular/specific coin on the spot trading account
in javascript.

So far i am requesting

  • the Account Information (USER_DATA) (from spot account/trade
    Binance API Documentation)
  • i build an array
  • i sub-build / request the coin i am interested in
  • then i save the value of the free amount of the coin (either crypto or fiat)

Is there an immidiate way to store this value without the previous steps?

Thanx in advance for your time.

With Mida it’s like this

import { login, } from "@reiryoku/mida";

const myAccount = await login("Binance/Spot", {
    apiKey: "***",
    apiSecret: "***",

const balance = await myAccount.getAssetBalance("ETH");
