Installation

pip install laplace-python-sdk

Quick Start

from laplace import LaplaceClient

# Initialize the client
client = LaplaceClient(api_key="your-api-key")

# Get stock details
stock = client.stocks.get_detail_by_symbol(symbol="AAPL", region="us")
print(f"{stock.name}: {stock.description}")

# Get all stocks in a region
stocks = client.stocks.get_all(region="us", page=1, page_size=10)
for stock in stocks:
    print(f"{stock.symbol}: {stock.name}")

# Get collections
collections = client.collections.get_collections(region="tr", locale="en")
for collection in collections:
    print(f"{collection.title}: {collection.num_stocks} stocks")

# Get collection details
collection_detail = client.collections.get_collection_detail(
    collection_id="620f455a0187ade00bb0d55f",
    region="tr"
)
print(f"Stocks in {collection_detail.title}:")
for stock in collection_detail.stocks:
    print(f"  {stock.symbol}: {stock.name}")

# Get politicians and their holdings
politicians = client.politicians.get_politicians()
for politician in politicians:
    print(f"{politician.politician_name}: {politician.total_holdings} holdings")

# Get holdings for a specific stock
holdings = client.politicians.get_politician_holdings_by_symbol("AAPL")
for holding in holdings:
    print(f"{holding.politician_name}: {holding.holding} ({holding.allocation})")

WebSocket Client (Live Price Data)

import asyncio
from laplace import LaplaceClient, LivePriceFeed, WebSocketOptions, LogLevel

# Initialize the client
client = LaplaceClient(api_key="your-api-key")

# Create WebSocket options
options = WebSocketOptions(
    enable_logging=True,
    log_level=LogLevel.INFO,
    reconnect_attempts=5,
    reconnect_delay=5000,
    max_reconnect_delay=30000,
)

# Create WebSocket client
websocket_client = client.create_websocket_client(
    feeds=[LivePriceFeed.LIVE_BIST, LivePriceFeed.LIVE_US],
    external_user_id="your-user-id",
    options=options,
)

# Define callback function for price updates
def on_price_update(data):
    print(f"Price update for {data.symbol}: {data.close_price}")
    if hasattr(data, 'percent_change'):
        print(f"  Change: {data.percent_change}%")
    print(f"  Timestamp: {data.timestamp}")

async def main():
    # Connect to WebSocket
    await websocket_client.connect()

    # Subscribe to symbols
    symbols_bist = ["THYAO", "GARAN", "AKBNK"]
    symbols_us = ["AAPL", "GOOGL", "MSFT"]

    # Subscribe to BIST symbols
    unsubscribe_bist = websocket_client.subscribe(
        symbols=symbols_bist,
        feed=LivePriceFeed.LIVE_BIST,
        handler=on_price_update
    )

    # Subscribe to US symbols
    unsubscribe_us = websocket_client.subscribe(
        symbols=symbols_us,
        feed=LivePriceFeed.LIVE_US,
        handler=on_price_update
    )

    # Keep connection alive
    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        # Cleanup
        unsubscribe_bist()
        unsubscribe_us()
        await websocket_client.close()

# Run the WebSocket client
asyncio.run(main())

Error Handling

from laplace import LaplaceClient, LaplaceAPIError

client = LaplaceClient(api_key="your-api-key")

try:
    stock = client.stocks.get_detail_by_symbol(symbol="INVALID", region="us")
except LaplaceAPIError as e:
    print(f"API Error: {e}")
    print(f"Status Code: {e.status_code}")
    print(f"Response: {e.response}")

Authentication

Get your API key from the Laplace platform and initialize the client:

client = LaplaceClient(api_key="your-api-key-here")
