Ethereum API Error: “Not Found, Unauthenticated, or Illegal”

As a developer working with the Binance API through the popular Python library, you’re probably no stranger to errors that can occur when interacting with financial platforms. Today, we’re going to dive into one specific error message that can be caused by an issue with the Ethereum API: “APIError(code=-1099): Not Found, Unauthenticated, or Illegal.”

Error Message Breakdown

Let’s break down the error code and message to better understand what could be going on:

• APIError: This is a standard Python error object that indicates an error encountered during an API request.

• code=-1099: In this case, the error code indicates that the Ethereum blockchain API returned a “404 Not Found” response. However, it seems that there’s a different issue here, as the 404 status code usually indicates an unknown resource or the server was not found.

• “Not Found”: This line further confirms that the API was unable to find any data or information about Ethereum transactions or balances.

• “unauthenticated” and “illegal”: These lines indicate that the request was not properly authenticated, which is another crucial aspect of interacting with the Ethereum blockchain.

Possible Causes

There are several possible causes for this error:

• Invalid API Endpoint: Make sure you are using the correct endpoint to retrieve Ethereum data. You can check the Binance API documentation to verify the supported endpoints and any specific requirements.

• Authentication Issues: Make sure that the application is properly authenticated with a valid API key or token. If the authentication is incorrect, it may result in illegal requests or errors like this.

• Network Connection Issues: Check your network connection to make sure you can establish a stable connection to the Binance API servers.

• API Rate Limiting: The Ethereum blockchain API has rate limits. If your application exceeds these limits, it may encounter errors like the following.

Recommendations

To resolve this issue, consider the following steps:

• Confirm API Credentials: Double-check that you are using the correct API key and token for your application.

• Check Network Connection: Make sure that your network connection is stable and working properly.

• Adjust API Endpoints and Rate Limits

  : Verify that you are using the correct endpoint and adjust the rate limits according to the Binance API documentation.

Python Code Example

Here is a sample Python code snippet showing how to handle this error:

“` python

import requests

Set API credentials and URL

api_key = “YOUR_API_KEY”

api_secret = “YOUR_API_SECRET”

endpoint = f”

try:

Create a new request with the appropriate parameters

params = {

“symbol”: “ETHUDT”,

Replace with the desired asset pair

“side”: “buy”

Buy or sell?

}

response = requests.post(endpoint, json=params)

Check if the API returned any error messages

if response.status_code != 200:

print(f”API error: {response.text}”)

If authentication issues were detected, try again with an authenticated request

api_key = “YOUR_AUTHENTICATED_API_KEY”

params [“fire_key”] = fire_key

endpoint = f”

response = requests.post(endpoint, json=params)

if response.code_status == 200:

print(f”API error: {response.text}”)

else:

print (“API error: “, response.
