Ethereum: Problems that place a Binanța Trade -API with Python
As a developer, it is interesting to explore new APIs and trade platforms, especially when you have to do with cryptocurrencies such as Ethereum. However, I came up with some problems when I tried to put business in the American version of Binance Api with Python without external libraries.
In this article, I will outline the challenges I have been with, I will make solutions and give a solution that you can use to successfully do business on the Binance API.
Challenges:
- Authentication
: The Binance API requires authentication chips, which are usually obtained by an oautoth flow or password-based authentication.
- API key : Each user has its own API key, which must be replaced before creating commercial requests for a binnation -po -token (BEP20).
- Interest limits : Binance -api has interest limits for the number of surveys per hour, which means that their ability to create business can often be limited.
Problem debts:
Use Oautoth Flow
To overcome the authentication issues with an Oautoth flow:
- Install the libraries “Requirements” and “Oautothlib”:
`Bash
PIP installs Oautlib questions
- Generați un client -ID și un secret pentru binance -API în aplicația dvs .:
Python
Customer_id = 'your_client_id'
customer_secret = 'your_client_secret'
3 .. Create an OAWH supplier object with the -ID customer, secret and URI (https: // api.binance.com/API/V3/Auth2/Callback):
`Python
Import questions
Oautoth_provider = oautothprovider (
Customer_id = Custom_id,
customer_secret = client_secret,
Redirect_uri = 'https: //your-pp-url.com/callback'
)))
Remove the user in the Oautth Supplier's -uru Authorization around
URL = oautoth_provider.Get_autothorize_url ()
Treat the recall from the Oautoth supplier
Def Authorize_Callback (Code):
Replace -with your own code for treatment response
happen
Make a commercial request with the API Bep20 token (BEP20)
Trade_request = {
"Symbol": "Etusdt",
"Page": "Buy",
"Type": "limit"
}
Answer = requirements.post (
F'Https: //pi.binance.com/api/v3/Tickers/ethusdt? symbol = {trade_request ["symbol"]} ',,
Antets = {'x-gx-apikey': oautoth_provider.get_token (code)}
)))
Process the answer
Use a password -based authentication
To overcome authentication issues using a password -based authentication:
- Create a Binance token -ap (Bep20) for your app.
Python
Import questions
API_TOKEN = 'your_api_toS
- Make a commercial request with the BEP20 token -API:
Python
Trade_request = {
"Symbol": "Etusdt",
"Page": "Buy",
"Type": "limit"
}
Answer = requirements.post (
F'Https: //pi.binance.com/api/v3/Tickers/ethusdt? symbol = {trade_request ["symbol"]} ',,
Headers = {'x-gx-apikey': api_token}
)))
Process the answer
`
Installation limit and interest limit exceptions
To avoid restrictive errors:
- Create API requests in Statuct to minimize the number of questions per hour.
- Exceptions of the tranche limit by repetition Requirements failed with a smaller size of the lot.
Diploma:
It may be a challenge to create business with binance -without external libraries, but there are ways to overcome these problems. Using Oautth Flow or password-based authentication and management rate limits, you can use Python to successfully introduce business on the American version of the Binance API. Remember to replace placeholder with your own values.
