The Alpaca Corporate Actions API: Announcements provides access to an extensive corporate actions database, offering detailed information on previous and upcoming dividends, mergers, spinoffs, and stock splits. The API allows users to stay up-to-date on upcoming announcements that may impact current holdings or assess potential investments, simplify bookkeeping, and support trading strategies based on corporate action events. Users can interact with the data dating back to April 2020, but bespoke reorganization announcements are not currently available. The API supports various query parameters, including type, symbol, CUSIP, and date range, enabling users to retrieve general or specific announcement information.
