Ethereum API Error: Duplicate Values ​​for parameter ‘Symols’

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 use 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 or 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 Retrieveing ​​Ethereum Prices. Some endpoints may have specific requirements or restrictions on parameters.

  • API Rate Limiting : The Ethereum API HAS Rate Limits in place to prevention abuse. If your code is exeding thesis 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 retrieveing ​​Ethereum Prices.

  • Limit Parameters : Instead of Using A Large List of Symols, Try Limiting Your Request to a Smaller Set of Values. You can use the limit parameter to specific the number of values ​​to return.

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

Code Example:

`Python

import requests

Define Your Ethereum API Endpoint and Parameters

API_endpoint = "

Params = {

'Symols': ['Eth', 'LTC'],

Retrieve Prices for Two Symols 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)

Github Documentation:

For more information on using the ethereum api, please refer to the official github documentation:

  • [Ethereum API] (

By following thesis steps and adjusting your code accordingly, you should be able to resolve the duplicate values ​​error and successully retrieve prices for multiple ethereum symbols.
