UK beneficial owners (PSC register, Companies House, live)

GB: UK beneficial owners (PSC, persons with significant control) live from Companies House for AML, KYB and compliance: individual and corporate-entity PSCs with natures of control (ownership/voting bands), notification dates, plus official PSC statements. Ceased PSCs excluded by default (inclure_cesses=true adds them with their ceased date). Beyond French-registry parity — France exposes no open UBO register. Month+year of birth only, no addresses. Open Government Licence v3.0 (Companies House). Preserve coverage and provenance. Missing data is not zero; a name match is not proof of identity.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
