    Why it is in this group

    • The name "get_activist_stakes" says "get": a word for reading.
    Description, as the server wrote it
    Get Schedule 13D/13G beneficial-ownership filings (activist and 5%+ large-holder stakes) for one company - ticker is required. Returns one row per filing with filer names and the maximum reported percent of class; detailed item narrative text is not included. event_revision is always null for these forms (a fact of the form, not missing data). Data delayed 24 hours (known_at); recent filings only.

    Why it is in this group

    • The name "get_company_timeline" says "get": a word for reading.
    Description, as the server wrote it
    Get one merged, time-ordered feed of SEC insider activity for a company: Form 4 events, Schedule 13D/13G stake filings, and Form 144 sale notices, distinguished by the source_form field (form4 | sc13 | form144). The limit applies after merging, so companies with heavy Form 4 activity can crowd out 13D/G and 144 rows - use the dedicated tools for those. Unknown tickers fail with an error (404). Data delayed 24 hours (known_at); no price-derived fields.

    Why it is in this group

    • The name "get_sale_notices" says "get": a word for reading.
    Description, as the server wrote it
    Get Form 144 notices of proposed insider sales for one company - ticker is required. shares_to_sell and aggregate_market_value are as-filed intentions announced before the sale, not executed trades - the matching Form 4 sale, if any, typically follows about a day later. event_revision is always null for this form. Data delayed 24 hours (known_at); recent filings only.

    Why it is in this group

    • The name "search_insider_events" says "search": a word for reading.
    Description, as the server wrote it
    Search interpreted insider-trading events from SEC Form 4 filings. Each event classifies raw filing rows into economic meaning (OPEN_MARKET_BUY vs EQUITY_AWARD vs TAX_WITHHOLDING_ONLY etc.), separating discretionary trades from compensation noise. Supports filtering by ticker, event type, minimum USD value, and time, with cursor pagination. Form 4 only - for 13D/G stakes or Form 144 sale notices use get_activist_stakes, get_sale_notices, or get_company_timeline. Data delayed 24 hours (known_at); history ~1 month; no price-derived fields.
