polygon 0.9.5

A Complete Python Wrapper for Polygon.io APIs. Public Alpha Release

polygon: A Polygon.io API Wrapper

what is polygon

polygon is a Complete Python Wrapper for Polygon.io APIs. It offers simple and elegant programmatic access over each endpoint. Functionalities include but not limited to:

• Stocks and Options data
• Forex and Crypto data
• Websocket streaming (both callback and async based)
• Market Info, News, Holidays, Schedules
• Async support for REST endpoints
• Built In stream reconnection functionality (only async stream, callback stream in progress)
• Pagination support (next/previous pages)

and more...

How do I use polygon

The complete description of everything you need to know is available in the Documentation which has answers to any question you might have with example uses included wherever needed. Docs is a must-read for most people.

More examples will be added to this repository in a folder examples as they are ready.

Here is a quick setup guide with a few examples

Before you do anything, you'll need to have a polygon account and get your API key. Visit your dashboard to get your API key.

Next, you'd need to install polygon

pip install polygon

and You're good to Go! A few quick examples.

Getting a stock's current market price

import polygon

api_key = 'YOUR_KEY'

stocks_client = polygon.StocksClient(api_key)

current_price = stocks_client.get_current_price('AMD')

print(current_price)

An Async example for REST endpoints - current price

import polygon
import asyncio

async def main():
    api_key = 'YOUR_KEY'
    
    stocks_client = polygon.StocksClient(api_key, True)
    
    current_price = await stocks_client.get_current_price('AMD')
    await stocks_client.close()  # Recommended to close the httpx session when it's not needed. 
    print(current_price)

if __name__ == '__main__':
    asyncio.run(main())

A streaming example (callback based)

import polygon
from polygon.enums import StreamCluster

def my_own_message_handler(ws, msg):
    print(f'msg received: {msg}')

def main():
    api_key = 'YOUR_KEY'

    stream_client = polygon.StreamClient(api_key, StreamCluster.STOCKS, on_message=my_own_message_handler)
    stream_client.start_stream_thread()
    stream_client.subscribe_stock_trades(['AMD', 'NVDA'])

if __name__ == '__main__':
    main()

An Async streaming example

import asyncio
import polygon
from polygon.enums import StreamCluster

async def stock_trades_handler(msg):   # it is possible to create one common message handler for different services.
    print(f'msg received: {msg}')
    
async def main():
    api_key = 'YOUR_KEY'
    
    stream_client = polygon.AsyncStreamClient(api_key, StreamCluster.STOCKS)
    
    await stream_client.subscribe_stock_trades(['AMD', 'NVDA'], stock_trades_handler)
    
    while 1:
        await stream_client.handle_messages()  # the lib provides auto reconnect functionality. See docs for info
if __name__ == '__main__':
    asyncio.run(main())

This only scratches the surface of the library.

See the Documentation to start using the library with its full functionalities.
