# Lodestar Stamp > Lodestar Stamp publishes dated checks of public sources for people and software. Each receipt identifies the business, checked fields, evidence and check dates. Public receipts and corrections are free. Watching delivers a baseline briefing and later published changes for the exact selected business. A public interface does not establish adoption by any assistant or booking platform. We verify source facts. We do not approve the booking. Payment never touches the record. > > Live seal: GET https://lodestarstamp.com/v1/seal?domain= (or ?license=) — VERIFIED / n OF m VERIFIED / NOT YET CHECKED. ## Status Pilot.
