13F institutional holdings (parsed) API

What a big investment manager owns: we find the latest SEC Form 13F-HR filing, locate its information-table XML, and PARSE it into clean holdings (issuer, CUSIP, value, shares), biggest first. Answers 'what does Berkshire own', '13F holdings for this fund', 'top positions of this manager'. Pass the manager's CIK (or a ticker like BRK-B).
