Get USD trading pair value via Binance API

When creating a bot that uses Binance API, it is essential to understand how to retrieve the value of each USD trading pair. Binance API provides a robust set of endpoints and parameters to retrieve market data, including currency conversion rates.

In this article, we will explore two methods to achieve this: using the fetchMarketData endpoint and leveraging a pre-built library to calculate exchange rates.

Method 1: Using the fetchMarketData endpoint

The fetchMarketData endpoint allows you to retrieve market data for a specific pair of symbols. To get the USD trading pair value, you need to specify the base currency (USD) and the symbol(s) of interest.

Here is a sample code snippet in Python using the Binance API client library (binance-api-client):

import binance_api_client





Set up your Binance API credentials
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

Create a Binance API client instance
client = binance_api_client.BinanceAPIClient(api_key, api_secret)

Define the base currency and symbol(s) of interest
base_currency = 'USD'
symbols = ['BTC/USDT', 'ETH/USDT']

Get market data for each pair
results = []
for symbol in symbols:
result = client.fetch_market_data(symbol=symbol)
results.append(result)

Extract current price values ​​from response
prices = [result['price'] for result in results]
print(prices)

Method 2: Using a prebuilt library

A popular alternative to manually fetching market data is to use a prebuilt library like binance-api-python. This library provides an easy-to-use API client that can be integrated into your bot.

Here is a sample code snippet in Python using the binance-api-python library:

import binance_api

Set up your Binance API credentials
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'

Create a Binance API client instance
client = binance_api.BinanceAPIClient(api_key, api_secret)

Define the base currency and symbol(s) of interest
base_currency = 'USD'
symbols = ['BTC/USDT', 'ETH/USDT']

Get market data for each pair
results = []
for symbol in symbols:
result = client.get_exchange_data(symbol=symbol)
prices = [result['price']]
results.append(prices)
print(prices)

Both of these methods should give you the value of USD trading pairs. However, keep in mind that using a pre-built library may be less scalable and require more setup time.

Tips and Variations

  • To get real-time exchange rates, use the fetchRealtimeMarketData endpoint instead of fetchMarketData.
  • You can also retrieve currency conversion rates by specifying the pair parameter in the get_exchange_data method.
  • If you need to retrieve multiple trading pairs or symbols at once, consider using a loop or list comprehension.

By following these steps and examples, you should be able to successfully get the value of USD trading pairs using Binance API.
