Ethereum: Questions with Binance API by using Python
As a developer, it is exciting to explore new APIs and commerce platforms, especially when dealing with cryptocurrencies such as Ethereum. At the same time, I encountered some problems while trying the Binance API American version without the Python external libraries.
In this article, I outline the challenges I face, offer solutions, and offer a solution to successfully facilitate the Binance API transactions.
Challenges:
- Authentication : Binance API requires authentication tokens that are usually obtained by Oauth flow or password-based authentication.
- API Keys : Each user has their own API key that must be replaced by the Binance API token (BEP20) before submitting commercial applications.
- Interest Restrictions : Binance API has a limit on the number of hourly requests that may limit the ability to exercise transactions.

Use
Oauth flow
To overcome authentication problems with Oauth Flow:
1
`Bash
PIP installation requests Oauthlib
`
- Make a customer ID and secret to Binance API for your application:
`Python
Client_id = ‘your_client_id’
client_secret = ‘your_client_secret’
`
- Create an Oauth service object with the customer ID, secret and redirection URI (which is
https: // api.binance.com/api/v3/auth/oauth2/ return):
Python
import requests
oauth_provider = oauthprovider (
Client_id = client_id,
client_secret = client_secret,
Redirect_uri = ‘https: //your-app-url.com/callback’
)
Redirect the user to the Oauth provider’s licensing URL
URL = oauth_provider.get_authorize_url ()
Manage the recall of Oauth provider
Def Authiventize_Callback (Code):
Replace your own code to manage a recall response
pass
Make a trading request using the BeP20 API TOKEN (BP20)
Tray_request = {
‘Symbol’: ‘zeldt’,
‘Side’: ‘Buy’,
‘type’: ‘limit’
}
Answer = request.Post (
f’https: //api.binance.com/api/v3/tickers/ethusdt? symbol = {trade_request [“symbol”]} ‘,
Headers = {‘X-MBX-APIKEY’: Oauth_Provider.get_token (Code)}
)
Process the answer
`
using password-based authentication
To eliminate authentication problems with password-based authentication:
- Create a Binance API token (BP20) to apply:
`Python
import requests
api_token = ‘your_api_token’
`
- Submit a trading request with the help of BeP20 API token:
`Python
Tray_request = {
‘Symbol’: ‘zeldt’,
‘Side’: ‘Buy’,
‘type’: ‘limit’
}
Answer = request.Post (
f’https: //api.binance.com/api/v3/tickers/ethusdt? symbol = {trade_request [“symbol”]} ‘,
Headers = {‘X-MBX-APIKEY’: API_TOKEN}
)
Process the answer
`
Speed limit and ratio restrictions are exceptions
To avoid speed limit errors:
- Prepare API requests in items to minimize the number of hours per hour.

Conclusion:
It may be a challenge to make trade outside the Binance API, but there are ways to overcome these issues. Use Oauth Flow or password-based authentication and handling speed restrictions to successfully place trading on the US version of Binance API with Python. Don’t forget to replace the places with your own values.
