x402
war-tracker.com Vessel AIS Track (1-hour polyline) is a paid API for AI agents from war-tracker.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Returns the recent AIS position track (up to 1 hour of history) for a single vessel identified by IMO number, as an ordered list of lat/lon/speed/course points suitable for plotting.

How this service works
Recent AIS position polyline for one vessel by IMO. Response shape: `{imo, hours_requested, hours_effective, raw_points_in_window, downsample_step, points: [{captured_utc, lat, lon, sog, cog}, …]}` — ordered oldest-first so a client can plot the track without sorting. The `?hours=` parameter is currently clamped to 1 (anything wider is silently rolled back — the param stays in the route signature so we can ship longer windows as higher-priced tiers without a rename). When the raw window…
Output
A JSON object containing the IMO, hours requested, effective hours covered, raw point count in the window, downsample step, and an array of position points ordered oldest-first, each with captured_utc timestamp, lat, lon, speed over ground (sog in knots), and course over ground (cog in degrees).
Example use cases
Monitor tanker movements near chokepoint
“Pull the last hour of AIS positions for IMO 9683621 so I can see if it's changed course near the Strait of Hormuz — I need the full track to plot on our mapping dashboard.”
Verify vessel sanctions evasion patterns
“Get me the position history for IMO 8007739 over the past hour — I'm looking for any sudden course changes or loitering that might indicate it's avoiding detection in the Black Sea.”
Analyze ship routing during conflict
“Show me the movement track for vessel IMO 9876543 from the last hour with all the lat/lon waypoints ordered chronologically — I need to visualize whether it's taking a different path to avoid the conflict zone.”
Technical details
Endpoint
GEThttps://war-tracker.com/api/v1/vessels/:imo/trackWhen to prefer
Use this endpoint when you need a time-ordered polyline of recent vessel positions to plot a movement track, rather than just the latest single position. Ideal for visualizing ship routes, detecting course changes, or confirming a vessel's recent path in a conflict or sanctions-monitoring context. Prefer over the latest-position endpoint when trajectory context matters, not just current location.
Side effects
- Unknown IMO number returns empty points array or 404
- hours parameter silently clamped to 1 regardless of requested value
- Vessel not transmitting AIS — returns zero points or sparse track
- Stale data if vessel went dark — points may not reflect true position
- Rate limit or payment failure returns 402 or 429 error
