v2.0.1

Release Notes – Massive Python Client v2.0.1 (breaking changes)

This is a major breaking release of the Python client as part of our company rebrand from Polygon.io to Massive.com. Polygon.io has rebranded as Massive.com effective October 30, 2025. Existing API keys, accounts, and integrations continue to work exactly as before. The only change in this SDK is that it now defaults to the new API base at api.massive.com, while api.polygon.io remains supported for an extended period. You can still install the old client using pip install polygon-api-client too.

Breaking Changes

• The default REST API base URL has changed from api.polygon.io → api.massive.com.
• The default WebSocket base URL has changed from socket.polygon.io → socket.massive.com.
• The package name and import path have changed from polygon → massive.

No other breaking changes are introduced. Core functionality, endpoints, and method signatures remain identical.

Migration Guide

To upgrade:

pip install massive

Then update your imports:

from polygon import RESTClient # Old
from massive import RESTClient # New

All API keys, accounts, and integrations continue to function without modification. If you continue using the legacy polygon-api-client package, it will remain supported for an extended transition period.

ℹ️ Additional Information

• No changes to client methods, models, or response structures.
• Both API domains (polygon.io and massive.com) are fully operational in parallel.
• For full background, see our blog post: Polygon.io is Now Massive.
• For help, open an issue or contact support@massive.com.
