New SEC Filings Endpoints: 13F, Form 3 & Form 4

We’ve added support for three key new SEC filings endpoints covering institutional holdings and insider transactions.

• list_stocks_filings_13f() – SEC Form 13F filings data showing institutional investment manager holdings.
• list_stocks_filings_form_3() – SEC Form 3 filings reporting initial statements of beneficial ownership of securities by corporate insiders.
• list_stocks_filings_form_4() – SEC Form 4 filings reporting changes in beneficial ownership of securities filed by directors, officers, and 10%+ shareholders.

Check the docs for usage examples.

Fractional Shares Support

We’ve added full native support for fractional shares across all snapshot (v2 & v3), aggregate, and trades endpoints. New fields (fractional_volume, fractional_accumulated_volume, and fractional_size) preserve exact decimal precision (returned as strings) while keeping the original volume/size fields unchanged for full backward compatibility. This applies to EquityAgg (WebSocket), UniversalSnapshot, and v2 TickerSnapshot.

New SEC Filings Endpoints (beta)

We’ve added complete coverage for the new /stocks/filings/vX/* family of beta endpoints.

• list_stocks_filings_index() - master index of all SEC filings
• list_stocks_filings_10k_sections() - raw text sections from 10-K/10-Q filings (business, risk_factors, etc.)
• list_stocks_filings_8k_text() - parsed 8-K filings with item-level text
• list_stocks_filings_risk_factors() - categorized risk factors (with supporting text)
• list_stocks_taxonomies_risk_factors() - risk factor taxonomy/categories

Check the docs for usage examples.

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.
