kind: company
description: FleetMon was a Rostock, Germany based vessel tracking and maritime data provider (founded 2007) that operated
  one of the world's largest terrestrial AIS receiver networks and a documented REST API (apiv2.fleetmon.com) for vessel search,
  live and historical AIS positions, port calls, expected arrivals, ETA and voyage planning. Kpler acquired FleetMon alongside
  MarineTraffic in 2023, the FleetMon platform and API were phased out from January 2024 and migrated into MarineTraffic,
  and in September 2025 the combined AIS assets were unified under the Kpler AIS brand. As of 2026 the fleetmon.com domain,
  developer portal, and API no longer resolve - this entry preserves the final archived API surface and points to the Kpler
  / MarineTraffic successor services.
