  description: 'Polygon.io (rebranded as Massive in early 2026) exposes real-time

    and historical US equity market data via a REST API at

    `https://api.polygon.io`. This specification captures a

    representative subset of the Stocks API: aggregate bars and ticker

    reference. Authentication uses an API key, sent either as the

    `apiKey` query parameter or as `Authorization: Bearer <apiKey>`.
