When to use it

manager is the firm's name or SEC CIK; quarter is e.g. "2026Q2" (default: latest filed); issuer filters to holdings whose name or CUSIP matches. Returns manager, period, filed date, totalValue in USD, positions and holdings[] { issuer, class, cusip, value, shares, pctOfPortfolio, putCall }, largest first. Keyed by the MANAGER, not the company held, so it cannot answer "who owns Apple". Long US-listed positions only, filed up to 45 days after quarter end.

What it costs

$0.0100 per successful call — flat, with no plan, minimum or monthly fee. A call that fails validation is refused before it runs, so it is never charged.
