Ethereum: Getting real time data for a set of symbols from BINANCE API

Extracting real-time data from the Binance API using Python

In this article, we will look at how to extract real-time data for a character set from the Binance API using the binance-connector-python library.

Prerequisites

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

• Create a Binance API account and receive your API key

• Load the binance-connector-python library

Step 1: Authenticate with Binance API

Before extracting data, you need to authenticate with the Binance API using your API key. This can be done 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. Creating the Client object

Create a Client object that 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. Extract real-time data for symbols

To retrieve real-time data for a set of symbols, use the symbol parameter in your request. You can pass an array of characters to get data for multiple pairs:

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

This will return the latest information on 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 is an example of a code snippet demonstrating how to extract 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']}
otherwise:
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 get real-time data for multiple symbols using binance-connector-python. You can add more characters by adding them to the list and changing the loop.

Conclusion

In this article, we covered the basics of extracting real-time data from the Binance API using binance-connector-python. By following these steps and examples, you will be able to extract the latest information about several Binance symbols every 15 seconds. Remember to replace API key and secret with actual values ​​and always follow security and speed limiting recommendations when interacting with external APIs.
