It provides both REST and WebSocket interfaces to fetch stock trades, quotes, aggregated bars, and options chain data. The package wraps HTTP calls via urllib3 and WebSocket connections via websockets, handling authentication, pagination, and filtering transparently so you can focus on querying market data rather than managing API details.\n\nThe REST client supports automatic pagination by default, fetching all results across pages unless you disable it; it also exposes filter operators (.gt, .gte, .lt, .lte) for refining queries. The WebSocket client streams real-time tick data to a handler function you define. Both clients require an API key from Massive.com and support debug tracing to inspect requests and responses. The package targets Python 3.9 through 3.14 and is actively maintained, with the rebranding preserving backward compatibility so existing integrations continue to work.","worth_installing":"Yes. The package is actively maintained, has low install friction, carries no known vulnerabilities, and is MIT-licensed. Install it if you need programmatic access to Massive's market data APIs; the REST and WebSocket clients are straightforward to use and handle pagination and filtering for you. The main gotcha is that you must obtain an API key and be aware of free-tier rate limits."},"id":"massive","links":{"html":"https://skillfed.io/packages/massive","md":"https://skillfed.io/packages/massive.md","pypi":"https://pypi.org/project/massive/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-26","license_spdx":null,"license_treatment":"permissive","name":"massive","python_support":"supports_current","summary":"Official Massive (formerly Polygon.io) REST and Websocket client."},"popularity":{"monthly_downloads":280289,"position":8113,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.8.0"}
