Here’s an article on obtaining Real-Time Ethereum Data without Blocking Code:
obtaining Real-Time Ethereum Data With Binance Websocket
As a developer, you’re likely familiar with the importance of having real-time data at your fingertips. In this article, we’ll explore how to get and plot real-time Ethereum data from Binance using Python’s Websocket Protocol.
Prerequisites
Before we dive into the code, make sure you have:
- A Binance API Key (For Authentication Purposes)
- A python 3.x Environment set up with a library of your choice
Importing Libraries and Configuring Binance API
`python
Import Websocket
Import pandas as pd
Set Up Binance API Credentials
api_key = "your_api_key"
api_secret = "your_api_secret"
Create a Websocket Object with the API Endpoint (Replace with your own)
ws = websocket.websocket ()
ws.connect ("WSS: //apis.binance.com/1/subapi")
DEFINING A CUSTOM EVENT HANDLER
To receive real-time data, we need to define an event handler that listens for incoming messages from Binance. We’ll use the on_message 'method provided by the websocket object.
python
Def Handle_Message (Message):
Try:
Parse the message as json
data = json.loads (message)
Extract Relevant Fields (We'll Ignore Eth Price and Exchange Rate for Now)
Symbol = Data ["Symbol"]
timestamp = you (date ["timestamp"])
Plot a simple line chart using pandas
df = pd.dataframe ({
'Date': [timestamp],
'ETH Price': [Date ["Open"] * 10000]
})
Display the plot (optional)
Import matplotlib.pyplot as plt
plt.plot (DF ['Date'], DF ['ETH Price'])
plt.show ()
Except JSON.JSONDECODEERROR:
Print (f "Invalid Message Received: {Message}")
Sending a Real-Time Plot Request to Binance
To plot Real-Time Data, we need to serve a request to Binance With Our Custom Event Handler. We’ll use the websocket_client
library to create a websocket object and send messages.
`python
Def Send_Plot_request (Symbol):
Try:
Create a Message With the Symbol and Timestamp (In Seconds Since Epoch)
msg = {
"JSONRPC": "2.0",
"method": "eth_getrealtimeblocktimes",
"Params": [
["USDT", 1, "timestamp"],
{"symbol": symbol}
],
"ID": 1
}
Send the Message to Binance and Get the Response
ws.send (JSON.Dumps (MSG) .encode ())
Parse the response as json
data = json.loads (ws.recv ()). Get ("Result")
Extract Relevant Fields (We'll Ignore Eth Price for Now)
Blocktimes = Data ["Blocktimes"]
BlockNumber = Int (Blocktimes [0])
Plot a simple line chart using pandas
df = pd.dataframe ({
'Block number': [BlockNumber],
'Timestamp': [You (Blocktimes [1])
})
Display the plot (optional)
Import matplotlib.pyplot as plt
plt.plot (DF ['Timestamp'], DF ['Block Number'])
plt.show ()
Except Exception As E:
Print (F "Error Sending Plot Request: {E}")
putting it all together
Here’s the complete code that combines all the steps:
“ python
Import Websocket
Import pandas as pd
Set Up Binance API Credentials
api_key = “your_api_key”
api_secret = “your_api_secret”
Create a Websocket Object with the API Endpoint (Replace with your own)
ws = websocket.websocket ()
ws.connect (“WSS: //apis.binance.com/1/subapi”)
Def Handle_Message (Message):
Try:
Parse the message as json
DATE = JSON.
