19Search SEC Form 4 insider transactions. Filter by ticker, insider, transaction type, date range, and more. Use exclude_10b5=true for discretionary-only signal analysis.
Get the most recent SEC Form 4 filings, optionally filtered by ticker.
Get a single Form 4 filing by its SEC accession number.

Get company profile — name, CIK, SIC sector, state of incorporation, website, filing counts.
List all insiders who have filed Form 4s for a company.
Get cluster buy/sell signals — multiple insiders at the same company transacting in the same direction within a short window. Excludes 10b5-1 plan trades automatically (no scraping-based tool does this). Requires Business plan.
List Form 144 notice-of-proposed-sale filings. Insiders disclose intent to sell ~2 days before the actual Form 4 sale lands — early signal on discretionary vs pre-scheduled sales. Filter by ticker, insider name, date range, or exclude 10b5-1 plans. Requires Business plan.
List institutional positions from Form 13F-HR filings. Filter by ticker (CUSIP→ticker resolved automatically), CUSIP, manager CIK, quarter, or minimum position value. Use this to find "who owns NVDA" or "which managers added to AAPL last quarter". Requires Business plan.
Browse the institutional manager index — each manager with their latest 13F-HR filing and AUM. Filter by name (partial match — "Berkshire" returns Berkshire Hathaway) or minimum AUM. Pair with get_holdings to see what a given manager owns. Requires Business plan.
Get the monthly insider-sentiment score for a ticker (MSPR-style, -100 to +100). Automatically excludes 10b5-1 plan trades — the score reflects actual insider conviction, not pre-scheduled dispositions. Requires Business plan.
Get an aggregate career rollup for a single insider by CIK: first/last transaction, total bought/sold/net, top companies, transaction-code breakdown, 10b5-1 plan split, post-trade return averages. Requires Pro plan.
