Get value of trading pair in USD

Question

I'm building a bot that uses Binance API, and i want to get the value of each trading pair in USD like in their App (check the screenshot), is there a way to acheive this using their API? or the only way is to convert each pair to USD value programmatically, because there is about 1542 trading pairs.

Answer 1

The Binance API has a symbol price ticker endpoint that returns a price when it receives a pair e.g. DOGE and USD would be "DOGEUSD" and would return something like {'symbol': 'ETHBTC', 'price': '0.06045300'}

Idk anything about JS etc., but in python I can get the price of a symbol by using get_symbol_ticker module from the Python Binance library like this:

from binance.client import Client
client = Client(api_key, api_secret, tld='us')
client.get_symbol_ticker(symbol="DOGEUSD")

Assuming this node package works the same way, then you could try something like this(copy-pasted, again I have never touched JS):

const Binance = require('node-binance-api');
const binance = new Binance().options({
  APIKEY: '<key>',
  APISECRET: '<secret>'
});

binance.prices('BNBBTC', (error, ticker) => {
  console.info("Price of BNB: ", ticker.BNBBTC);
});

ANYWAYS, once you get the prices it's just a matter of mathing.

ethbtc = client.get_symbol_ticker(symbol="ETHBTC") # response `{'symbol': 'ETHBTC', 'price': '0.06045300'}`
btcusd = client.get_symbol_ticker(symbol="BTCUSD") # response {'symbol': 'BTCUSD', 'price': '32620.8700'}
float(btcusd["price"]) * float(ethbtc["price"]) # returns 1968.48369144

float(BTCUSD["price"]) takes {'symbol': 'BTCUSD', 'price': '32581.0800'} and returns USD per BTC i.e. 32581.08.

Getting BTCUSD and ETHBTC current prices allows us to find out USD per BTC per 1xETH or how many USD costs to buy enough BTC to exchange for a single ETH which at current rates is roughly 1 ETH == 0.060433 BTC == $1968.48

EDIT 1: Get-Products API

As demonstrated here, you can get all the products and a list of their OHLCV values using the get-products API call. Example:

var url = "https://www.binance.us/exchange-api/v1/public/asset-service/product/get-products";

var xhr = new XMLHttpRequest();
xhr.open("GET", url);

xhr.onreadystatechange = function () {
   if (xhr.readyState === 4) {
      console.log(xhr.status);
      console.log(xhr.responseText);
   }};

xhr.send();
