FleetMon Historical Track API API

swagger: '2.0'
info:
  description: 'ARCHIVED SPECIFICATION - RETIRED API. This is the final publicly archived Swagger 2.0 definition of the FleetMon API (apiv2.fleetmon.com), preserved from the Internet Archive Wayback Machine (schema.json capture 2021-12-08; the developer portal at developer.fleetmon.com remained online through early 2025). FleetMon was acquired by Kpler in 2023, the FleetMon platform and API were phased out beginning January 2024 and migrated into MarineTraffic, and as of 2026 the fleetmon.com domain (including apiv2.fleetmon.com and developer.fleetmon.com) no longer resolves. None of the endpoints below are live. The successor surface is the MarineTraffic API portfolio / Kpler AIS (servicedocs.marinetraffic.com).
