Getting the Order Book List with Binance API: A Step-by-Step Guide

As an Ethereum developer, understanding how to access order book information is crucial for building robust trading platforms or integrations. In this article, we’ll show you how to retrieve the order book list using the Binance API.

Prerequisites

• Create a Binance API account and obtain your API key and secret.

• Install the requests library in Python (available on PyPI) if you haven’t already.

• Import the necessary libraries: requests and json.

Step 1: Set up your API credentials

In your Binance API dashboard, create a new application or select an existing one. In the “API Credentials” section, obtain your:

• API Secret Key: This is used to authenticate your requests.

• Public API Key: This is required for most API calls.

Step 2: Construct the API request

You can use the following code snippet to construct a GET request to retrieve the order book list:

import requests


api_key = 'YOUR_API_KEY'

api_secret = 'YOUR_API_SECRET'


base_url = at 

headers = {

    'X-MBX-APIKEY': api_key,

    'X-MBX-SECRET-PASS': api_secret

}


params = {'symbol': 'ETH', 'limit': 100} 




Set the symbol to ETH and limit to 100 orders


response = requests.get(base_url, headers=headers, params=params)


if response.status_code == 200:

    data = response.json()

    print(date)

otherwise:

    print(in Error: {response.text}')

Step 3: Parse the order book information

The orderbook section of the response contains a dictionary with the following keys:

• openOrders: The list of open orders.

• closedOrders: The list of closed orders.

• takersBySide: A map of taker symbols to lists of orders.

• bids: A list of bids.

• asks: A list of questions.

We’ll extract the following information:

• Open orders (openOrders): The list of open orders with their side, price, quantity, and time.

• Closed orders (closedOrders): The list of closed orders with their side, price, quantity, and time.

• Taker symbols to lists of orders (takersBySide): Maps taker symbols to lists of orders.

Step 4: Output the order book information

We’ll output the extracted data in a format suitable for display:

Get the list of open orders

open_orders = data['orderbook']['openOrders']



Print the open orders with their side, price, quantity, and time

for order in open_orders:

    print(f"Side: {order['side']}, Price: {order['price'],}", end='\n')

Example Output

The output will look like this:

Side: Buy

Price: 2828.00

Quantity: 100


Side: Sell

Price: 2835.00

Quantity: 50

By following these steps, you should be able to retrieve the order book list using the Binance API. Remember to replace YOUR_API_KEY and YOUR_API_SECRET with your actual API credentials.

Tips and Variations

• To get the same information as the order book on Binance.com, use the /v3/openOrders endpoint instead of /v3/allOrders.

• You can filter the orders by using the limit parameter in the query string.

• You can also add additional parameters to the API request, such as symbol or time, to retrieve specific information.
