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 straits-live-premium-vessel-manifest-340a1931
```

Example prompt: Pull the full live vessel manifest for the Strait of Hormuz — I want to see all ships currently tracked by AIS, which ones are OFAC or UK sanctioned, their risk bands, and any vessels that have gone dark.

## When to prefer this

Use this endpoint when you need a comprehensive, live snapshot of all vessel traffic in the Strait of Hormuz with integrated OFAC/UK sanctions screening and AIS-dark detection in a single call. Prefer this over the aggregate crisis monitor endpoint when you need per-vessel MMSI-level detail, individual risk bands, or raw AIS positions rather than a high-level situation brief.

## Known failure modes

- 402 Payment Required — x402 payment of $0.02 USDC not provided or invalid
- 401 Unauthorized — missing or expired authentication credentials
- 503 Service Unavailable — upstream AIS data feed temporarily offline
- 429 Too Many Requests — rate limit exceeded
- Empty vessel list if AIS feed has a gap or no vessels are currently tracked in the strait

## How this service works

Strait of Hormuz per-vessel intelligence: the live-AIS vessel manifest (MMSI-keyed, flag derived from the MMSI MID), the OFAC-sanctioned vessels currently in the Persian Gulf window with program detail, per-vessel risk bands, latest raw AIS positions, the top AIS-dark hulls with the full dark count alongside, and OFAC + UK sanctions reference-list sizes (per-IMO multi-body detail at /api/premium/vessel/{imo}).

## Output

A MMSI-keyed JSON manifest of all vessels currently tracked in the Strait of Hormuz, including flag derived from MMSI MID, OFAC-sanctioned vessels with program detail, per-vessel risk band classifications, latest raw AIS position data, a list of AIS-dark (signal-lost) vessels, and the total count sizes of OFAC and UK sanctions reference lists. Per-IMO multi-body sanction detail is available at the /api/premium/vessel/{imo} sibling endpoint.
