A new real-time Benzinga News endpoint is now available, offering headline and full-text coverage with filtering by ticker and time. Ideal for monitoring, alerting, and dashboards. More information: https://massive.com/docs/rest/partner...

We’ve released four new financials APIs—income statements, balance sheets, cash flow statements, and daily-updated ratios—covering roughly 6,700 companies back to 2009. Explore the endpoints: https://massive.com/blog/announcing-p...

Our ETF Global partnership adds five new daily datasets including flows, constituents, profiles, exposure, and taxonomy data. Full details: https://massive.com/partners/etf-global

The NYSE order imbalance WebSocket feed is now available, offering real-time buy/sell pressure around opens, closes, and post-halt sessions, including paired shares and indicative clearing prices. Learn more: https://massive.com/docs/websocket/st...

As of November 3, our quotes API reports bid and ask sizes in shares rather than round lots to align with SEC MDIR requirements and updated SIP formats. Conversion guidance is available here: https://massive.com/blog/change-stock...

Finally, our futures product is in private beta, with expected expansion to general availability by year-end. Futures will have real-time and historical data via REST, WebSockets, and flat files. Sign-up information: https://massive.com/futures
