Market-wide recent Form 144 insider intent-to-sell notices across all US issuers
Market-wide recent Form 144 insider intent-to-sell notices across all US issuers — who is filing to sell, before the Form 4 confirms it. Per notice: ticker, issuer, insider, shares to be sold, aggregate market value, and approximate sale date. Tune the window with `?days=` (max 90) or `?startdt`/`?enddt`, and `?limit=` (max 50). Proposed sales, not executed. From SEC EDGAR. From x402stock
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
