SEC Form 13F Institutional & Hedge Fund Holdings API

Search official SEC EDGAR Form 13F-HR and 13F-HR/A filings by investment manager name or CIK, filing date, report quarter, issuer, CUSIP, value, shares, put/call, discretion, and amendment status. Use it for institutional holdings, hedge fund holdings, quarterly manager portfolios, and source-linked investment research with official filing, cover-document, information-table, and search URLs plus bounded-scan disclosure. Form 13F is lagged manager-filed disclosure—not SEC verification, a live or complete portfolio, beneficial-ownership proof, or investment advice. It can omit short positions, non-13(f) securities, and confidential holdings and can later be amended. Deterministic test: managerCik=1067983&maxResults=1&maxFilingsScanned=1 returns Berkshire Hathaway's source-linked American Express holding. MCP tool: search_sec_form_13f_holdings.
