  AISHub has a single, non-monetary access model - contribute-to-access. There
  are no paid tiers and no open free tier; instead, members earn free access to
  the aggregated network data (raw NMEA feed and the HTTP web service) by
  operating an AIS receiver and streaming at least one raw NMEA AIS feed to
  AISHub over UDP. API credentials are granted once the contributed feed meets
  published quality thresholds - coverage of at least 10 vessels and at least
  90% uptime over a rolling 7-day period, with message delays not exceeding 10
  seconds. The "price" of the API is your data contribution plus the cost of
  running your own receiver.
notes: >-
  No pricing page exists; no commercial/paid access route is documented on
  aishub.net. Commercial-use terms are not explicitly addressed in the public
  join documentation - members should confirm usage terms with AISHub.

    The only plan. Stream a raw NMEA AIS feed from your receiver to AISHub via
    UDP; once the feed meets the quality thresholds you receive an API
    username and free access to the aggregated data - vessel positions and
    station metadata via the HTTP web service (XML/JSON/CSV) plus the raw
    aggregated NMEA feed, a real-time monitoring dashboard, and feed-down
    alerts.
