Significant Update to Futures Beta Endpoints (Breaking Changes)

As part of our ongoing beta program for Futures data, we've made a key structural improvement by consolidating endpoints. Previously, we had separate endpoints for retrieving lists of all Futures items (e.g., contracts, products, or schedules) and for fetching details on specific ones. Now, we have single streamlined endpoints:

• /futures/vX/contracts: Handles both lists and specific contract details.
• /futures/vX/products: Covers product lists and individual product info.
• /futures/vX/schedules: Manages overall and product-specific schedules.
• /futures/vX/market-status: Enhanced for better market insights.

This consolidation simplifies integration and reduces API calls, but it introduces breaking changes.

New Endpoints for Expanded Coverage

We've added several new endpoints to enrich your toolkit:

• /benzinga/v1/bulls-bears-say: Sentiment analysis from bulls and bears.
• /fed/v1/labor-market: Insights into Federal Reserve labor market data.

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.
