The notification history of one person with significant control, by PSC id. A company's PSC list gives who controls it today; this returns the sequence of notifications filed about a single PSC — when the control was notified, its nature (ownership of shares in the 25-50%, 50-75% or 75-100% band, voting rights, the right to appoint or remove directors, significant influence), and when it ceased. Use it to establish WHEN control changed rather than only who holds it now, which is the question that matters for beneficial-ownership history and for dating a change of control. The psc_id is only ever obtained from a company's persons-with-significant-control list; it cannot be derived from a name.

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.
