Configuration File for Reading Ethereum API Key: Step by Step Guide for Beginners

Greeting! Congratulations on starting your coding journey, especially with trading bots. As a beginner, setting up and installing the necessary libraries and configurations for your bot can be overwhelming. In this article, we will walk you through how to read an Ethereum API key from a configuration file using Python.

Why are you struggling?

You get a SyntaxError: (unicode error)' message, indicating that there is a problem with the syntax of the code. Don't worry; It's easy to solve! In this article, we will focus on setting up the correct configuration and resolving the syntax error.

Create a new file calledconfig.jsonin the same directory as your trading bot script. This file will store your API key.

{

    "api_key": "YOUR_API_KEY_HERE",

    "api_secret_key": "YOUR_API_SECRET_KEY_HERE"

}

Replace YOUR_API_KEY_HEREandYOUR_API_SECRET_KEY_HEREwith your actual Binance API keys.

• requests: for making HTTP requests

• json: for parsing JSON data

pip installation requirements

pip install json

Open your config.jsonfile and add your Binance API key:

{

    "api_key": "YOUR_API_KEY_HERE",

    "api_secret_key": "YOUR_API_SECRET_KEY_HERE"

}

Modify your trading bot script (eg trading_bot.py`) to read the API key from the configuration file:

import requirements


def get_api_keys():

    api_key = None

    try:

        
Use configuration file to get API keys

        with open('config.json', 'r') as f:

            data = json.load(f)

            api_key = data['api_key']

        return api_key

    except for exceptions like e:

        print(f"Error reading API key from configuration file: {e}")



Get an API key and use it to submit a request

api_key = get_api_keys()

print(api_key) 
Output: YOUR_API_KEY_HERE



Make a request using the API key

url = "

headers = {'api_key': api_key, 'api_secret_key': 'YOUR_API_SECRET_KEY_HERE'}

response = requests.get(url, headers=headers)

print(response.json()) 
Output: JSON data from Binance API

Step 5: Start Your Trading Robot

Finally, run your trading bot script using Python:

python trading_bot.py

This should connect to the Ethereum API test and print your API key.

That’s it! You have successfully read the Ethereum API key from the configuration file and used it in your trading bot. Don’t forget to update your code with your own Binance API keys when you’re ready for production use. Good luck and happy coding!
