Ethereum API Error: “Not Found, Not Authenticated, or Not Authorized”

As a developer working with the Binance API via the popular Python library, you’re probably familiar with the errors that can occur when interacting with financial platforms. Today, we’ll cover a specific error message that can be caused by an issue with the Ethereum API: APIError(code=-1099): Not Found, Not Authenticated, or Not Authorized.

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 appears that there’s another issue at play here, as the 404 status code usually signifies an unknown or unfound resource on a 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 authenticated properly, which is another crucial aspect of interacting with the Ethereum blockchain.

Possible Causes

There are several potential causes for this error:

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

• Authentication issues: Make sure your application is authenticated correctly using a valid API key or access token. If the authentication is incorrect, it can lead to unauthorized requests or errors like this.

• Network connectivity issues: Check your network connectivity to ensure you can establish a stable connection with the Binance API servers.

• API Rate Limiting: The Ethereum blockchain API has usage rate limits. If your application exceeds these limits, you may encounter errors like this.

Recommendations

To resolve this issue, consider the following steps:

• Check your API credentials

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

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

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

Python Code Example

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

« `Python

import requests

Configure 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

parameters = {

« symbol »: « ETHUSDT »,

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 are detected, retry with an authenticated request

api_key = « AU_AUTHENT_API_KEY »

params[« api_key »] = api_key

endpoint = f »

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

if response.status_code == 200:

print(f »API Error: {response.text} »)

else:

print(« API Error: « , response.
