Use it when

To see which group a target belongs to, or what a buyer already owns.

What it does

Who owns a company and what it owns: its direct and ultimate parents and its subsidiaries from GLEIF, a US listed company's subsidiaries from its 10-K (Exhibit 21), parents and subsidiaries Wikidata records, and in the UK the people and companies with significant control and how (shares, votes, the board). People by name and role only. Notes say what a register doesn't publish. Nothing is charged when nothing is found.

What comes back

found, parents (relation, name, id or wikidata, country, source), owners (name, kind, control, since, source), subsidiaries (name, id, country or jurisdiction, source), subsidiaries_total, notes on what the registers don't publish, and sources. Every reply also carries cost_usd and balance_usd.
