Retrieving Real-Time Data from Binance API with Python

In this article, we’ll explore how to retrieve real-time data for a set of symbols from the Binance API using the binance-connector-python library.

Prerequisites

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

• Create a Binance API account and obtain your API key

• Download the binance-connector-python library

Step 1: Authenticate with Binance API

Before retrieving data, you need to authenticate with the Binance API using your API key. You can do this by creating a Config object:

import binance.connector as bc


class Config:

    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 Real-Time Data for Symbols

To retrieve real-time 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 about both 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 with the current market data:

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

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

Example Code

Here’s an example code snippet that demonstrates 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 = 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 pairs:

            data = self.client.symbol(symbol=pair)

            

            if time:

                return {'data': data, 'timestamp': data['timestamp']}

            else:

                return {
data, {'data': None}}


if __name__ == '__main__':

    retriever = RealTimeDataRetriever()

    for symbol in ['BTCUSDT', 'ETHUSDT']:

        print(retriever.get_real_time_data(symbol=symbol))

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

Conclusion

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