# StatePulse Marine Vessel Live Telemetry

> StatePulse Marine Vessel Live Telemetry is a paid API for AI agents from statepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Looks up real-time AIS position, speed, heading, and destination data for a marine vessel by MMSI number

## Facts

- Endpoint: POST https://statepulse-api.hahavoid0.workers.dev/transit/marine-vessel
- Price: $0.15/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability statepulse-marine-vessel-live-telemetry-e5b8151a -d '<json body>'
```

Example prompt: Can you look up the live position, speed, and destination of the vessel with MMSI 205792000 — I want to know where it is right now and where it's headed?

## When to prefer this

Use this endpoint when you need real-time AIS-based position, heading, speed, and destination for a specific marine vessel identified by MMSI number. Prefer this over general shipping APIs when you want pay-per-call access with no API key via x402 USDC payments on Base.

## Known failure modes

- MMSI not found or vessel not currently broadcasting AIS — supported: false returned
- Stale or low-confidence AIS data — confidence field will be 'low'
- Invalid MMSI format — may return error or unsupported result
- Vessel in AIS dead zone or inland — no position data available
- Payment failure via x402 — request blocked before processing

## How this service works

Resolves the current coordinate telemetry and voyage details for a cargo ship by MMSI number. Matches: cargo ship location tracker, AIS transponder coordinate lookup, find container vessel by MMSI, ocean logistics cargo positioning, track shipping container vessel, sea lanes transit tracker.

## Output

Returns a JSON object with the vessel's MMSI, current latitude and longitude, destination port name, speed in knots, vessel name, course in degrees, and a confidence rating (e.g. 'medium') along with a 'supported' flag indicating whether live AIS data was available for the MMSI.
