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 severe 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 are 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 are 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.

Example Code:

`python

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.
