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

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

Error Message Breakdown

Let’s break down the error code and message to better understand what might be happening:

• APIError: This is a standard Python error object that represents 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 is another problem here, as the 404 status code usually means an unknown resource or one not found on the server.

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

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

Possible Causes

There are several possible reasons for this error:

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

• Authentication Issues: Make sure your application is properly authenticated using a valid API key or access token. If the authentication is incorrect, it may result in unauthorized requests or similar errors.

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

• API Rate Limit: There are rate limits for using the Ethereum blockchain API. If your application exceeds these limits, it may encounter errors like this.

Recommendations

To resolve this issue, follow these steps:

• Check your API credentials

  : Check that you are using the correct API key and access token for your application.

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

• Adjust API endpoints and rate limits: Make sure that you are using the correct endpoint and adjust the rate limits according to the Binance API documentation.

Example Python Code

Here is an example Python code snippet to demonstrate how to handle this error:

“` python

import requests

Specify API credentials and URL

api_key = “YOUR_API_KEY”

api_secret = “YOUR_API_SECRET”

endpoint = f”

try:

Create a new request with the correct 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 errors

if response.statuscode != 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[“api_key”] = api_avain

endpoint = f”

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

if response.statuscode == 200:

print(f”API error: {response.text}”)

else:

print(“API error: “, response.
