The official Python client library for the Massive.com (formerly Polygon.io) REST and WebSocket APIs, providing access to stock, options, forex, crypto, and indices market data. It wraps API endpoints with typed methods, automatic pagination, and real-time streaming support.
Use cases
- fetch historical stock price bars in python
- stream real-time stock trades and quotes via websocket
- get last trade and quote for a ticker
- download market data for backtesting strategies
- integrate polygon.io market data into a python app
- paginate through large trade datasets
When to choose
- you need programmatic access to Massive/Polygon market data from Python
- you want automatic pagination and typed responses for REST endpoints
- you need real-time streaming market data in Python applications
When to avoid
- you use another language like JavaScript, Go, or Java - use the official client for that language
- you need bulk historical datasets better served by Massive Flat Files
- you want an MCP/AI-agent integration rather than a Python SDK
