Ethereum: Binance API. Duplicate values for parameter ‘symbols’

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

The Ethereum API error you encountered occurs when there are duplicate values ​​for a certain parameter, in this case « characters ». This can happen if you try to get prices for multiple symbols at the same time using the same API endpoint.

Reason:

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

  • Using too many parameters: Ethereum APIs usually have a limited number of parameters that can be used together. If you are asking to get prices for multiple symbols, it is 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 to receive Ethereum coins. Some endpoints may have special parameter requirements or restrictions.
  • API Rate Limit: The Ethereum API has rate limits to prevent abuse. If your code exceeds these limits, it will throw an error when trying to retrieve duplicate values.

Solution:

To solve this problem, you can try the following steps:

  • Use the correct API endpoint and URL: Make sure you are using the correct endpoint and URL to receive your Ethereum coins.
  • Limit the parameters: Instead of using a large list of characters, try limiting your query to a smaller set of values. You can use the limit parameter to specify the number of values ​​to return.
  • Use a second API method: If you are asking to load multiple characters with a single API call, consider using a second API method that allows you to load multiple characters in a single call.

Example Code:

Python

import requests

Define the Ethereum API endpoint and parameters

api_endpoint = « 

parameters = {

‘symbols’: [‘ETH’, ‘LTC’],

Get prices of two symbols simultaneously

‘limit’: 10,

Limit the number of returned values

}

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, parameters=parameters, headers={‘X-API-KEY’: api_key})

Check if the response was submitted successfully

if response.status_code == 200:

Parse the JSON response and get the prices for each character

data = response.json()

for symbol in [‘ETH’, ‘LTC’]:

price = data[symbol][‘price’]

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

more:

print(« Error: », response.status_code)

« `

GitHub documentation:

More information on using the Ethereum API can be found in the official GitHub documentation:

  • [Ethereum API](

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 tokens.
