Ethereum: Issues Placing a Trade with Binance API using Python
As a developer, it’s exciting to explore new APIs and platforms for trading, especially when dealing with cryptocurrencies like Ethereum. However, I’ve encountered some issues while trying to place trades on the US version of Binance API using Python without external libraries.
In this article, I’ll outline the challenges I faced, provide workarounds, and offer a solution to help you successfully make trades on the Binance API.
Challenges:
- Authentication
: The Binance API requires authentication tokens, which are usually obtained through an OAuth flow or password-based authentication.
- API keys: Each user has their own API key, which needs to be exchanged for a Binance API token (BEP20) before making trade requests.
- Rate limits: The Binance API has rate limits on the number of requests per hour, which can limit your ability to make trades frequently.
Workarounds:
Using OAuth Flow
To overcome authentication issues using an OAuth flow:
- Install
requestsandoauthliblibraries:
pip install requests oauthlib
- Generate a client ID and secret for the Binance API in your application:
client_id = 'your_client_id'
client_secret = 'your_client_secret'
- Create an OAuth provider object using the client ID, secret, and redirect URI (which is
import requests
oauth_provider = OAuthProvider(
client_id=client_id,
client_secret=client_secret,
redirect_uri='
)
Redirect the user to the OAuth provider's authorization URL
url = oauth_provider.get_authorize_url()
Handle the callback from the OAuth provider
def authorize_callback(code):
Replace with your own code for handling the callback response
pass
Make a trade request using the BEP20 API token (BEP20)
trade_request = {
'symbol': 'ETHUSDT',
'side': 'buy',
'type': 'limit'
}
response = requests.post(
f'
headers={'X-MBX-APIKEY': oauth_provider.get_token(code)}
)
Process the response
Using Password-Based Authentication
To overcome authentication issues using password-based authentication:
- Create a Binance API token (BEP20) for your application:
import requests
api_token = 'your_api_token'
- Make a trade request using the BEP20 API token:
trade_request = {
'symbol': 'ETHUSDT',
'side': 'buy',
'type': 'limit'
}
response = requests.post(
f'
headers={'X-MBX-APIKEY': api_token}
)
Process the response
Rate Limiting and Rate Limit Exceptions
To avoid rate limiting errors:
- Make API requests in batches to minimize the number of requests per hour.
- Handle rate limit exceptions by retrying failed requests with a smaller batch size.
Conclusion:
Making trades on the Binance API without external libraries can be challenging, but there are ways to overcome these issues. By using OAuth flow or password-based authentication and handling rate limits, you can successfully place trades on the US version of the Binance API using Python. Remember to replace placeholders with your own values.
