Ethereum API Error: Duplicate Values for Parameter ‘symbols’

The Ethereum API error you’re experiencing occurs when there are duplicate values for a specific parameter, in this case, symbols. This can happen if you try to retrieve the prices of multiple symbols simultaneously using the same API endpoint.

Cause:

There are several reasons why your code might be encountering this issue. Here are some possible causes and solutions:

• Using too many parameters

  

  : Ethereum APIs typically have a limited number of parameters that can be used together. If you’re trying to retrieve prices for multiple symbols, it’s likely that one of the values is redundant or identical to another parameter.

• Using the wrong API endpoint: Make sure you’re using the correct API endpoint and URL for retrieving Ethereum prices. Some endpoints may have specific requirements or restrictions on parameters.

• API rate limiting

  : The Ethereum API has rate limits in place to prevent abuse. If your code is exceeding these limits, it will throw an error when trying to retrieve duplicate values.

Solution:

To fix this issue, you can try the following:

• Use the correct API endpoint and URL: Ensure that you’re using the correct endpoint and URL for retrieving Ethereum prices.

• Limit parameters: Instead of using a large list of symbols, try limiting your request to a smaller set of values. You can use the limit parameter to specify the number of values to return.

• Use a different API method: If you’re trying to retrieve multiple symbols with a single API call, consider using a different API method that allows for multi-symbol retrieval in a single call.

Code example:

import requests



Define your Ethereum API endpoint and parameters

api_endpoint = "

params = {

    'symbols': ['ETH', 'LTC'],  
Retrieve prices for two symbols at once

    'limit': 10,  
Limit the number of values returned

}



Set your API key (replace with your actual API key)

api_key = "YOUR_API_KEY_HERE"



Make a GET request to the Ethereum API endpoint

response = requests.get(api_endpoint, params=params, headers={'X-API-KEY': api_key})



Check if the response was successful

if response.status_code == 200:

    
Parse the JSON response and retrieve prices for each symbol

    data = response.json()

    for symbol in ['ETH', 'LTC']:

        price = data[symbol]['price']

        print(f"Price for {symbol}: ${price:.2f}")

else:

    print("Error:", response.status_code)

By following these steps and adjusting your code accordingly, you should be able to resolve the duplicate values error and successfully retrieve prices for multiple Ethereum symbols.
