Ethereum API Key Read Configuration File: A Beginner’s Guide
Greetings! Congratulations on starting your programming journey, especially with trading bots. For a beginner, setting up and installing the necessary libraries and configurations for your bot can be a difficult task. In this article, we’ll show you how to read the Ethereum API key configuration file using Python.
Why are you fighting?
You will see a “SyntaxError: (unicode error)” message indicating that there is a problem with the syntax of your code. Don’t worry; it’s easy to solve! In this article, we will focus on determining the correct configuration and eliminating the syntax error.
Qualifications
Before proceeding with the instructions, make sure that you have:
- Python is installed on your computer
- Binance Ethereum API test key (or any other Ethereum API)
- Basics of Python programming
Step 1: Select the location of the configuration file
Create a new file named “config.json” in the same directory as the trading bot script. This file stores your API key.
Example config.json:
{
"api_key": "YOUR_API_KEY_HERE",
"api_secret_key": "YOUR_API_SECRET_KEY_HERE"
}
Replace YOUR_API_KEY_HERE and YOUR_API_SECRET_KEY_HERE with your actual Binance API keys.
Step 2: Install Required Libraries
You need to install the following libraries:
requests: to perform HTTP requests
json: for parsing JSON data
Run the following commands in the terminal:
requests to install pip
pip install json
Step 3: Read the API key from the configuration file
Open the “config.json” file and add the Binance API key:
{
"api_key": "YOUR_API_KEY_HERE",
"api_secret_key": "YOUR_API_SECRET_KEY_HERE"
}
Save the changes to the configuration file.
Step 4: Update the trading bot script
Modify the trading bot script (e.g. trading_bot.py) so that it reads the API key from the configuration file:
import requests
definition of get_api_keys():
api_key = None
to ask:
Use the configuration file to get the API keys
where open('config.json', 'r') f:
data = json.load(f)
api_key = data['api_key']
return api_key
except for an exception of type e:
print(f"Error reading API key from configuration file: {e}")
Get the API key and use it to execute the request
api_key = get_api_keys()
print(api_key)
Print: YOUR_API_KEY_HERE
Make a request with your 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())
Result: JSON data from the Binance API
Step 5: Launch your trading bot
Finally, run the trading bot script using Python:
python trading_bot.py
This should connect to the Ethereum test API and print your API key.
That’s it! You successfully read the Ethereum API key from the configuration file and use it in your trading bot. Don’t forget to update your code using Binance’s own API keys when you’re ready for production. Good luck and happy programming!
