SEC 13F — institutional ownership, asked security-first.

From the maker's README Institutional ownership from SEC Form 13F, asked security-first. Hosted, keyless to the caller. Deltas are a first-class citizen here, not an afterthought: managerchanges and securityflows answer "what changed" directly, because a static holdings snapshot isn't a newsletter — a change is.

  What one institutional manager NEW-ed, EXITED, INCREASED or DECREASED between two 13F quarters — the newsletter primitive: a portfolio snapshot is not news, a change is.

Give the manager name ("Berkshire Hathaway", "Pershing Square"). Returns each holding with value and share count, plus the reported quarter. For what CHANGED since th

  Which institutional managers hold a given US-listed security, ranked by position size — the reverse of every 13F API, which requires you to name the manager first. Give a company name, ticker (e.g. "NVDA") or 9-character CUSIP. Ticker input is resolved through OpenFIGI, not a bulk symbol table. Retu
