Error Management in Binance API for Klines Date Speaking
When working with Binance API to retrieve the Klines data, it is common to experience errors that can be difficult to troubleshoot. In this article we discuss some possible questions and give an updated code example that addresses these challenges.
1. Release: Invalid or missing API credentials
Make sure you typed api_key and“ api_secret ”correctly into the“ client ”constructor:
`Python
from the binance.client import client
Client = client (api_key, api_secret)
2. Edition: Incorrect request method or URL structure
The Binance API expects the Get request to retrieve the clines. Make sure you use the correct request method and format the URL accordingly.
Here’s an updated example with error handling:
`Python
Import pandas as PD
Def get_kklines_data (symbol, period):
"" "
Clin data from Binance API to a specific symbol and period.
Args:
Symbol (str): the cryptocurrency symbol (such as BTC/USD)
Period (you): Duration of seconds (such as 1D, 3D, etc.)
Back:
List: A list of clines objects containing price and open prices for the specified symbol and period.
"" "
Try:
Create a binance client copy with valid API credentials
Client = client (api_key, api_secret)
Determine the requirement parameters (replace your own data)
params = {{
"Symbol": symbol,
"Period": Periodic
}
Download Klines data using get request
Answer = client.get_kklines (params = params)
Check that API has returned -e error
If 'error' in response:
Print ("API Error:", Answer ['Error'] ['Message'])
Return
Subtract and form the Klines data to Pandas Dataframe
Klines_Data = Pd.Dataframe
Return the extracted clines data
Return Klines_Data
Except for the exception like E:
Print ("Error:", Str (E)))
Return
Using examples:
Symbol = "BTC/USD"
Period = 1*60
1 minute period
klines_data = get_klines_data (symbol, period)
If the Klines_Data is not: None:
Print (Klines_Data)
More tips:
- Be sure to handle errors and exceptions properly, as they can be difficult to troubleshoot.
- Use an attempt to get a block to catch specific exception types such as “httperror” or time limit.
- Consider the use of Binance API built-in error handling mechanisms, such as the “TRY EXPECEPEPT-FINAL” block.
- If you experience problems with data formatting or analysis, make sure your applicant is correct and formed accordingly.
By following these guidelines and examples, you should be able to successfully retrieve the Klines from the Binance API with the help of Python.
