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
limitparameter 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)

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.
