# SiteCheck Trade & Energy – IMO Vessel Dossier

> SiteCheck Trade & Energy – IMO Vessel Dossier is a paid API for AI agents from api.tradeenergy-api.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns comprehensive ship particulars for a vessel identified by IMO number, combining AIS-derived data from VesselFinder with registry data from BalticShipping's vessel register.

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 sitecheck-trade-energy-imo-vessel-dossier-a91fbd13
```

Example prompt: Can you pull up the full vessel dossier for IMO 9321483 — I need the owner, manager, class society, flag, gross tonnage, and builder details?

## When to prefer this

Use this endpoint when you need a rich, combined vessel profile from both live AIS particulars and static registry data in a single call. Prefer it over a pure AIS endpoint when you need builder, owner, manager, or class society — fields that AIS does not carry. Best for due diligence, sanctions screening prep, charter vetting, or trade compliance research where knowing both the technical specs and the commercial/legal identity of a vessel matters.

## Known failure modes

- IMO number not found in either source — returns empty or partial record
- BalticShipping registry data missing for the vessel — owner/manager/class fields absent
- VesselFinder page unavailable — AIS-derived fields (MMSI, draught, nav status) missing
- Malformed or non-7-digit IMO number — input validation error
- Registry data stale — owner and class society information may be years old

## How this service works

Ship particulars by IMO number: name, type, flag, MMSI, call sign, year built, gross tonnage, length and beam, current draught and navigation status from VesselFinder's public page, plus deadweight, builder, engine, owner, manager and class society (when listed) from BalticShipping's public vessel register, with that record's last update date. Owner and class data can be years old.

## Output

A combined vessel profile including: name, type, flag, MMSI, call sign, year built, gross tonnage, length, beam, current draught, navigation status (from VesselFinder AIS), plus deadweight, builder, engine details, owner, manager, class society, and last registry update date (from BalticShipping). Some fields like owner, class, and manager may be absent or years old depending on registry coverage.
