Fetching Real-Time Data from Binance API with Python

In this article, we will explore how to extract real-time data for a set of symbols 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 your API key

• Download the binance-connector-python library

Step 1: Log in to Binance API

Before you can retrieve your data, you need to log in to Binance API using your API key. You can do this by creating a Config object:

import binance.connector as bc
classConfig:
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, which is used to interact with the Binance API:

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

Step 3: Retrieve live data for symbols

To retrieve 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 on BTC/USD and ETH/USD.

Step 4: Get real-time data for each symbol

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

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

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

Sample Code

Here is a sample code snippet demonstrating how to get live data for multiple symbols using binance-connector-python:

import binance.connector as bc
class RealTimeDataRetriever:
def __init__(self):
self.config = Config()
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 pair in pair:
data = self.client.symbol(symbol=pair)
if now:
return {'date': date, 'timestamp': data['timestamp']}
else:
return {
date, {'date': none}}
if __name__ == '__main__':
retriever = RealTimeDataRetriever()
for symbol in ['BTCUSDT', 'ETHUSDT']:
print(retriever.get_real_time_data(symbol=symbol))

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

Conclusion

In this article, we covered the basics of retrieving real-time data from the Binance API using binance-connector-python. Following these steps and examples, you should be able to retrieve the latest information on multiple Binance tokens every 15 seconds. Remember to replace your API key and secret with actual values ​​and always follow security and rate limiting best practices when interacting with external APIs.
