Ownership

The institutional and insider picture for a company: 13F holders and their positions, and the insider summary — built by the platform’s position engine, which reconciles each filing against the ones before it rather than trusting any single form.
Insider transactions from Forms 3, 4 and 5, newest first. filter is All, Sales, Purchases, Awards or Other; derivatives=true includes derivative-security rows; pageSize is 1–100. astreus ownership NVDA --transactions --filter Purchases is the terminal form.

​
Management

Officers and directors as disclosed in proxy statements and annual reports, leadership changes from 8-K Item 5.02, and shareholder-vote results from Item 5.07.

​
People

The registry of executives, directors and institutions across the universe. role narrows to people, officers, directors or institutions; ticker to those attached to one company; currentOnly=1 to people with a filing in the last two years; sort is featured, recent, name, companies or accuracy (guidance track record).
One person — roles and tenure across companies, holdings, and their guidance track record where they have given guidance — plus their insider transactions across every company they have filed for, and a photo (public route, image bytes). {cik} is the person’s SEC CIK for US filers, or a platform person key (XDFMP…) for people known only through exchange-lane filings.

Historical and programmatic research

/companies/{id}/ownership/insider-history and /ownership/nationality-history serve different ownership time series. Keep each observation’s date, share class, reported denominator and source; a reported position does not establish a live beneficial-ownership percentage. Transactions can be bounded by date and owner. MCP get_ownership, get_management, search_people and get_person expose their bounded research views. Tool responses may omit photos, analyst contact details and other fields that are not available for redistribution. The tool reference maps each route to its tool and CLI operation. For a member of Congress, /people/{cik}/votes returns recorded roll calls with Congress and page filters. This is a public-record dataset separate from insider security transactions; available=false means it is not held for that person.
