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




Ethereum: Binance API. Duplicate values for parameter 'symbols'

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.
