## Tools (as reported by the server, not verified)

- `check\_vessel`: Screen one vessel by IMO number against OFAC SDN, EU, UN, UK OFSI and OpenSanctions, with an ownership-opacity score and an A–E vetting grade from port-state-control history. Works with no API key. Rate-limited to 100 requests per hour per IP. Returns the VERDICT SUMMARY only; for every sanctions ma
- `find\_port`: Resolve a port name, country or partial UN/LOCODE to the LOCODEs the routing engine knows. Routes are addressed by LOCODE, so call this before score\_voyage rather than guessing a code. Works with no API key.
- `screen\_vessel`: The authenticated screening record for one vessel: every sanctions match with its source list, programme and confidence class, ownership opacity, the graded vetting factors, per-source freshness, and a retained record id. Needs ARCNAUTICAL\_API\_KEY. Metered: a new self-serve key includes a one-time f
- `screen\_vessels`: Batch-screen a list of IMO numbers and wait for the results \(up to two minutes\). Returns one verdict per hull plus the batch status. Needs ARCNAUTICAL\_API\_KEY. Each hull spends one screening unit unless it was already screened today.
- `get\_screening`: Fetch a stored screening record by id — the audit copy, retained ten years. Needs ARCNAUTICAL\_API\_KEY.
- `score\_voyage`: Route risk between two ports \(UN/LOCODEs\): a 0–100 score, risk level, the signals driving it \(war-risk areas, piracy, chokepoints, weather, sanctions exposure of transited EEZs\), confidence and any missing sources. Resolve port names with find\_port first. Needs ARCNAUTICAL\_API\_KEY; 10,000 assessment
- `get\_usage`: Live and test usage, remaining allowance, reset time, batch limits and monitor capacity for the configured key.
