VesselFinder is a maritime intelligence company operating a global AIS vessel-tracking network (terrestrial AIS plus satellite AIS) and offering ship positions, voyage history, vessel particulars, port-call events, sea-distance routing, and ocean-container track-and-trace through its developer APIs. The platform pairs a credit-metered AIS REST API (Vessels, PortCalls, ExpectedArrivals, MasterData, Distance, plus subscription feeds VesselsList and LiveData) with a separate Container Tracking API that returns shipment schedules and real-time vessel positions by container number. VesselFinder also runs a public web map, iOS/Android apps, an embeddable map widget, a fleet explorer, and a route planner.
