Cubesphere Insider

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.

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.
