Retrieving Ethereum Account Details on Binance with Python-Binance

As a cryptocurrency enthusiast, you are probably familiar with the importance of monitoring your account details regularly. One convenient way to achieve this is by connecting to the Binance API and retrieving your account information using the python-binance library. However, I encountered an issue where the script was unable to retrieve the expected account details.

The Problem:

When trying to connect to the Binance API using Python-Binance version 0.7.9, I encountered an AttributeError: Object 'NoneType' has no attribute 'encode'. This error message suggests that the library expects an object with a specific attribute called encode, but instead, it receives None.

The Solution:

After some research and debugging, I identified the root cause of this issue:

• API Request Format: Binance’s API request format has changed since the last release. Specifically, the account_get method used in Python-Binance requires an additional parameter to specify the API endpoint. In the previous version (0.5.x), there was no need to pass any parameter to get the account details. However, in the latest version (0.7.x) and later, this parameter is required.

Here is a revised script that should work with Python-Binance version 0.7.9:

import os
import json
def get_account_details():









Replace with your API key
api_key = "YOUR_API_KEY"

Replace with your secret key (if prompted to generate one)
api_secret = "YOUR_API_SECRET"

Set the API endpoint and parameters
endpoint = " account_get"
params = {
"apikey": api_key,
"secret": api_secret,
"language": "en_US",

Add your preferred API version (e.g. 2, 3, etc.)
"v": "1" if os.environ.get("BINANCE_API_VERSION") == '1' else "2"
}
try:

Make the API request
response = requests.post(endpoint, params=params)

Parse the JSON response
data = json.loads(response.text)

Extract account details and return them
if data["data"]:
result = {
"account_id": data["data"]["id"],
"account_balance": float(data["data"]["balance"]),
"account_address": data["data"]["address"]
}
print(json.dumps(result, indent=4))
else:
print("No account details found")
except requests.exceptions.RequestException as e:
print(f"Error: {e}")

Run the function to retrieve account details
get_account_details()

Note: This script will use the default API version (1 in this case) unless you have set the BINANCE_API_VERSION environment variable. Replace “YOUR_API_KEY” and “YOUR_API_SECRET” with your actual Binance API credentials.

By making these changes, your code should now successfully retrieve your Ethereum account details using Python-Binance without encountering the AttributeError: 'NoneType' object has no attribute 'encode' issue.
