Authentication Levels

1. Public Methods: Access market data without authentication
2. Private Methods: Require API keys for account-specific actions and order execution

Security Note: Always store your API keys securely in environment variables (.env file)!

Essential Unified Structures

• Market Structure: Defines trading pairs and quoting conventions
• Balance Structure: Organizes account funds and available balances
• Order Structure: Standardizes order notation across exchanges

Supported Programming Languages

# Python implementation
import ccxt
print(ccxt.exchanges)

// JavaScript/TypeScript implementation
const ccxt = require('ccxt');
console.log(ccxt.exchanges);

// PHP implementation
include 'ccxt.php';
var_dump(\ccxt\Exchange::$exchanges);

// C# (Beta) implementation
using ccxt;
Console.WriteLine(ccxt.Exchanges);

Getting Started with CCXT

Connecting to an Exchange

# Python connection example
binance = ccxt.binance({
    'apiKey': 'YOUR_BINANCE_API_KEY',  # Retrieve from environment variables
    'secret': 'YOUR_BINANCE_SECRET',   # Retrieve from environment variables
})

Troubleshooting Tip: If connection fails, verify the exchange's credential requirements.
