Binance API Documentation Guide: Seamlessly Integrate Cryptocurrency Features into Your App

1. What Is Binance API? Functions & Types Explained

1.1 Overview

Binance API empowers developers to access trading data, user account details, and execute trades programmatically. It bridges applications with Binance’s exchange ecosystem, enabling tools like trading bots, analytics dashboards, and crypto services.

1.2 Core Features

• Market Data: Fetch real-time prices, candlestick charts, and trade histories.
• Account Management: Check balances, order status, and withdrawal records.
• Trading: Place buy/sell orders or cancel requests.
• Real-Time Alerts: Subscribe to WebSocket for live updates.

1.3 API Types

Binance offers two primary interfaces:

• REST API: For batch data retrieval or single operations.
• WebSocket API: Ideal for real-time monitoring (e.g., price fluctuations).

2. Binance API Quickstart: Zero-to-Integration Guide

2.1 Setup API Keys

1. Register a Binance account (enable 2FA).

3. Advanced Binance API Techniques

3.1 Candlestick Data

Fetch hourly BTC/USDT K-lines:

params = {  
  "symbol": "BTCUSDT",  
  "interval": "1h",  
  "limit": 10  
}  
response = requests.get("https://api.binance.com/api/v3/klines", params=params)  

3.2 Placing Orders

Example (Python):

headers = {  
  "X-MBX-APIKEY": "YOUR_KEY",  
  "X-MBX-SECRET-KEY": "YOUR_SECRET"  
}  
order_params = {  
  "symbol": "BTCUSDT",  
  "side": "BUY",  
  "type": "LIMIT",  
  "quantity": 0.01,  
  "price": 45000  
}  
requests.post("https://api.binance.com/api/v3/order", headers=headers, json=order_params)  

3.3 WebSocket Live Data

JavaScript snippet:

const ws = new WebSocket('wss://stream.binance.com:9443/ws/btcusdt');  
ws.on('message', (event) => {  
  console.log('Price update:', JSON.parse(event));  
});
