Fetching Real-Time Data from Binance API Using Python

In this article, we will show you how to fetch real-time data for a symbol set from Binance API using the binance-connector-python library.

Prerequisites

• Install the required libraries: pip install binance-connector-python

• Create a Binance API account and get an API key

• Download the binance-connector-python library

Step 1: Authenticate with Binance API

Before fetching data, you need to authenticate with Binance API using your API key. This can be done by creating a Config object:

import binance.connector as bc
Class configuration:
Binance_API_KEY = 'YOUR_Binance_API_KEY'
Binance_API_SECRET = 'YOUR_Binance_API_SECRET'

Replace YOUR_Binance_API_KEY and YOUR_Binance_API_SECRET with your actual API key and secret.

Step 2: Create a Client Object

Create a Client object that will be used to interact with the Binance API:

client = bc.Client(api_key=Config.Binance_API_KEY,
api_secret=Config.Binance_API_SECRET)

Step 3: Get Live Data for Symbols

To get live data for a set of symbols, use the symbol parameter in your query. You can pass an array of symbols to get data for multiple pairs:

pairs = ['BTCUSDT', 'ETHUSDT'] 
list of symbols
client.symbol(symbol='BTCUSDT')

This will return the latest information for BTC/USD and ETH/USD.

Step 4: Get real-time data for each symbol

To get real-time data for each symbol, you need to use the symbol parameter with the time option set to True. This will return a dictionary containing the current market data:

client.symbol(symbol='BTCUSDT', time=True)

This will display the current price, volume, and other market data.

Sample code

Here is a sample code snippet that shows how to retrieve real-time data for multiple symbols using binance-connector-python:

import binance.connector as bc
class RealTimeDataRetriever:
def __init__(self):
self.config = Configuration()
self.client = bc.Client(api_key=self.config.Binance_API_KEY,
api_secret=self.config.Binance_API_SECRET)
def get_real_time_data(self, symbol=None, time=False):
if not symbol and time:
return {
'symbol': '',
'time': true
}
if not symbol:
raise ValueError('Symbol is required')
pairs = [symbol]
for pairs in pairs:
data = self.client.symbol(symbol=pair)
if time:
return {'data': data, 'timestamp': data['timestamp']}
else:
return {
data, {'data': None}}
if __name__ == '__main__':
discovery = RealTimeDataRetriever()
for symbol in ['BTCUSDT', 'ETHUSDT']:
print(retriever.get_real_time_data(symbol=symbol))

This code snippet shows how to retrieve real-time data for multiple symbols using binance-connector-python. You can add more symbols by adding them to the list and modifying the loop.

Conclusion

In this article, we will cover the basics of downloading real-time data from the Binance API using binance-connector-python. By following the steps and examples below, you should be able to download the latest information about different Binance symbols every 15 seconds. Remember to replace the API key and secret key with actual values, and always follow best practices for security and throttling when interacting with external APIs.
