FleetMon

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.

agent aware

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles FleetMon the way a machine reads it — 40 machine-readable artifacts across 37 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — FleetMon scores 21.6/100 (emerging), with a separate agent-readiness read of 41/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile FleetMon

Each block below is one kind of artifact we hold for FleetMon. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 37

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
