Extract Ethereum Price from Binance API in Python

============================================================

In this article, we will explain step by step how to save and update the latest Ethereum (ETH) price using Binance API in Python.

Prerequisites

—————

• You have installed the requests library (pip install requests) and the Binance API client library for Python (pip install binance-client)

• You have a Binance API account with sufficient funds and permissions to access the ETH market

• You have set up your API credentials in your Python script

Code

——

import os
import json
from binance.client import Client





Set your Binance API credentials
API_KEY = 'your_api_key'
API_SECRET = 'your_api_secret'

Create a new Binance client instance with your API credentials
client = Client(api_key=API_KEY, api_secret=API_SECRET)
def get_latest_eth_price():
"""
Get the latest ETH price from Binance's API.
Returns:
tuple: The latest ETH price and the corresponding exchange symbol (e.g. "ETHUSDT")
"""

Get list of available exchanges
exchanges = Client.get_exchanges()

Filter list to include only Ethereum (ETH) exchange
eth_exchange = [exchange for exchange in exchanges if exchange["symbol"] == "ETH"]

If no ETH exchange is found, raise error
if not eth_exchange:
raise ValueError("No ETH exchange found")

Get current price from ETH exchange
latest_price = eth_exchange[0]["latestPrice"]
return latest_price
def store_latest_eth_price(price):
"""
Store the current ETH price to a file.
Arguments:
Price (Float): The current ETH price to store.
"""
with open('latest_eth_prices.json', 'w') as f:
json.dump({'latestPrice': price, 'symbol': 'ETHUSDT'}, f)
def main():

Get the latest ETH price
latest_price = get_latest_eth_price()

Store the price in a file
store_latest_eth_price(latest_price['latestPrice'])
print(f'Latest ETH price stored: {latest_price["latestPrice"]} USD')
if __name__ == '__main__':
main()

Explanation

————–

• In the get_latest_eth_price function we create a new Binance client instance with our API credentials.

• Then we filter the list of available exchanges to include only the Ethereum (ETH) exchange using client.get_exchanges() method.

• If no ETH exchange is found, we raise an error.

• We fetch the latest price from the ETH exchange and store it in a dictionary for later use.

• In the store_latest_eth_price function, we open a file named latest_eth_prices.json in write mode ('w') and write our latest ETH price and symbol (ETHUSDT) in JSON format to the file.

• Finally, in the main function, we call the get_latest_eth_price function to get the latest ETH price and store it in a file.

Example Use Case

——————-

To use this script, save it as a Python file (e.g. eth_price_tracker.py) and run it with your Binance API credentials. The script will print the latest ETH price stored in the file. You can modify the script to suit your needs by adding additional functionality or error handling.

Note: Be sure to replace “Your API Key” and “Your API Secret” with your actual Binance API credentials.
