Polygon Provider¶
PolygonProvider remains available as a deprecated compatibility alias for
existing Polygon.io integrations. Polygon.io rebranded to Massive.com, and
existing Polygon API keys continue to work.
New code should use:
Set MASSIVE_API_KEY for new environments. Existing POLYGON_API_KEY values are
still supported.
See the canonical Massive provider documentation for current coverage, examples, and limitations.
