  title: VesselFinder AIS Containers Port Calls API
  description: 'REST API providing real-time and on-demand AIS vessel positions, voyage information,

    and vessel master data from the VesselFinder global AIS network (terrestrial and satellite).

    Authentication is performed via the `userkey` query parameter. Responses default to JSON

    and may be requested as XML by setting `format=xml`. Most pay-per-use methods deduct credits

    from the account''s balance; subscription methods (VesselsList, LiveData) are billed by fleet

    or area size and dataset selection.
