Ethereum API Error: Duplicate values ​​for ‘symbols’ parameters

The Ethereum API error occurs when a specific parameter, in this case symbols, has duplicate values. This can happen if you are trying to retrieve prices for multiple symbols at once using the same API endpoint.

Cause:

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

• Using too many parameters: The Ethereum API typically has a limited number of parameters that can be used together. If you are trying to retrieve prices for multiple symbols, it is possible that one of the values ​​is redundant or identical to another parameter.

• Using the wrong API endpoint: Make sure you are using the correct API endpoint and URL to retrieve Ethereum prices. Some endpoints may have specific requirements or parameter restrictions.

• API rate limit: The Ethereum API has rate limits in place to prevent abuse. If your code exceeds these limits, an error will be thrown when attempting to retrieve duplicate values.

Solution:

You can try the following steps to resolve this issue.

• Use the correct API endpoint and URL: Make sure you are using the correct endpoint and URL to retrieve Ethereum prices.

• Limit parameters: Instead of using a large list of symbols, try limiting the 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 are trying to retrieve multiple symbols with a single API call, consider using a different API method that allows you to retrieve multiple symbols in a single call.

Code example:

import requests









Define your Ethereum API endpoint and parameters
api_endpoint = "
parameters = {
'symbols': ['ETH', 'LTC'], 
Retrieve prices for two symbols at a time
'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 responses.status_code == 200:

Parse the JSON response and retrieve prices for each symbol
data = response.json()
for symbol ['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 value error and successfully retrieve prices for multiple Ethereum symbols.
