💻 Usage Examples

1. Get Bitcoin Price (Basic)

import asyncio
from mainserver import CryptoMCPServer, MarketDataRequest, Exchange

async def main():
    server = CryptoMCPServer()
    
    # Get current BTC price
    request = MarketDataRequest(
        symbol="BTC/USDT",
        exchange=Exchange.BINANCE
    )
    ticker = await server.get_ticker(request)
    
    print(f"BTC Price: ${ticker.last:,.2f}")
    print(f"24h Change: {ticker.change_24h:+.2f}%")
    print(f"Volume: {ticker.volume:,.0f}")

asyncio.run(main())

Output:

BTC Price: $43,256.78
24h Change: +2.34%
Volume: 1,234,567

2. Get Historical Data

from mainserver import HistoricalDataRequest, TimeFrame

async def get_history():
    server = CryptoMCPServer()
    
    # Get last 24 hours of hourly data
    request = HistoricalDataRequest(
        symbol="BTC/USDT",
        exchange=Exchange.BINANCE,
        timeframe=TimeFrame.H1,  # Hourly candles
        limit=24
    )
    
    candles = await server.get_ohlcv(request)
    
    print(f"Retrieved {len(candles)} hourly candles")
    for candle in candles[-5:]:  # Last 5 candles
        print(f"{candle.timestamp}: ${candle.close:,.2f}")

asyncio.run(get_history())

Output:

Retrieved 24 hourly candles
2025-11-15 18:00:00: $43,156.78
2025-11-15 19:00:00: $43,234.56
2025-11-15 20:00:00: $43,189.23
2025-11-15 21:00:00: $43,245.67
2025-11-15 22:00:00: $43,256.78

3. Multi-Exchange Price Comparison

async def compare_prices():
    server = CryptoMCPServer()
    
    # Compare BTC price across multiple exchanges
    prices = await server.get_multi_exchange_ticker(
        "BTC/USDT",
        [Exchange.BINANCE, Exchange.KRAKEN, Exchange.COINBASE]
    )
    
    print("BTC/USDT Price Comparison:")
    for exchange, ticker in prices.items():
        print(f"  {exchange:12} ${ticker.last:,.2f}")
    
    # Find best price
    best = min(prices.items(), key=lambda x: x[1].last)
    print(f"\nBest price on {best[0]}: ${best[1].last:,.2f}")

asyncio.run(compare_prices())

Output:

BTC/USDT Price Comparison:
  binance      $43,256.78
  kraken       $43,289.12
  coinbase     $43,267.45

Best price on binance: $43,256.78

4. Calculate Price Statistics

async def analyze_price():
    server = CryptoMCPServer()
    
    # Get 7 days of daily data
    request = HistoricalDataRequest(
        symbol="BTC/USDT",
        timeframe=TimeFrame.D1,
        limit=7
    )
    
    stats = await server.get_price_statistics(request)
    
    print(f"Weekly Statistics for {stats['symbol']}:")
    print(f"  Current Price: ${stats['current_price']:,.2f}")
    print(f"  Average Price: ${stats['average_price']:,.2f}")
    print(f"  High: ${stats['highest_price']:,.2f}")
    print(f"  Low: ${stats['lowest_price']:,.2f}")
    print(f"  Volatility: ${stats['volatility']:,.2f}")
    print(f"  Weekly Change: {stats['price_change_percent']:+.2f}%")

asyncio.run(analyze_price())

Output:

Weekly Statistics for BTC/USDT:
  Current Price: $43,256.78
  Average Price: $42,890.45
  High: $44,123.56
  Low: $41,234.89
  Volatility: $456.23
  Weekly Change: +3.45%

5. Get Order Book Depth

async def get_orderbook():
    server = CryptoMCPServer()
    
    request = MarketDataRequest(
        symbol="BTC/USDT",
        exchange=Exchange.BINANCE
    )
    
    orderbook = await server.get_orderbook(request, limit=5)
    
    print("Order Book:")
    print("\nTop 5 Asks (Sell Orders):")
    for i, (price, amount) in enumerate(orderbook.asks[:5], 1):
        print(f"  {i}. ${price:,.2f} × {amount:.4f} BTC")
    
    print("\nTop 5 Bids (Buy Orders):")
    for i, (price, amount) in enumerate(orderbook.bids[:5], 1):
        print(f"  {i}. ${price:,.2f} × {amount:.4f} BTC")
    
    spread = orderbook.asks[0][0] - orderbook.bids[0][0]
    print(f"\nBid-Ask Spread: ${spread:.2f}")

asyncio.run(get_orderbook())

6. Real-Time Price Monitor

async def price_monitor(symbol, threshold, duration=60):
    """Monitor price and alert when threshold crossed"""
    server = CryptoMCPServer()
    request = MarketDataRequest(symbol=symbol, exchange=Exchange.BINANCE)
    
    print(f"Monitoring {symbol}, alerting if > ${threshold:,.2f}")
    
    for _ in range(duration):
        ticker = await server.get_ticker(request)
        if ticker.last > threshold:
            print(f"🚨 ALERT! {symbol} is ${ticker.last:,.2f}")
            break
        print(f"Current: ${ticker.last:,.2f}", end='\r')
        await asyncio.sleep(1)

asyncio.run(price_monitor("BTC/USDT", 50000, duration=30))
