The REST client handles stock trades, quotes, aggregates (OHLCV bars), and options chains with automatic pagination by default, while the WebSocket client streams real-time tick data for subscribed symbols. The library abstracts away connection management, pagination logic, and API authentication, letting you focus on data retrieval.\n\nThe package depends on urllib3 for HTTP requests, websockets for real-time connections, and certifi for SSL certificate validation. It supports Python 3.9 and newer, with no system-level compiled dependencies. Pagination is enabled by default for list endpoints, meaning the limit parameter controls page size rather than total results\u2014you can disable this if you need a fixed result count. The client includes debug mode for inspecting request and response details.","worth_installing":"Yes. The package has low install friction, active maintenance, no known vulnerabilities, permissive licensing, and broad Python version support. It is the official client for a widely-used financial data API, making it the natural choice if you need Massive market data in Python. The main constraint is needing a valid API key and accepting the free tier's rate limits."},"id":"polygon-api-client","links":{"html":"https://skillfed.io/packages/polygon-api-client","md":"https://skillfed.io/packages/polygon-api-client.md","pypi":"https://pypi.org/project/polygon-api-client/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-10-30","license_spdx":null,"license_treatment":"permissive","name":"polygon-api-client","python_support":"supports_current","summary":"Official Polygon.io REST and Websocket client."},"popularity":{"monthly_downloads":793154,"position":5043,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.16.3"}
