search_insider_events

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.

Parameters6

ticker	any	optional	Stock ticker symbol to filter by, e.g. AAPL or TSLA. Omit to search across all companies.

get_company_timeline

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.

Parameters2

ticker	string	required	Stock ticker symbol of the company (issuer), e.g. AAPL or TSLA. Required.
limit	integer	optional	Maximum number of timeline items after merging all form types. Default 50, maximum 300.
