| Tool | Description | Behaviour |
|---|---|---|
| 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 match with its source list and confidence class use screen_vessel (needs a key). | Read-only |
| 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. | Read-only |
| get_screening | Fetch a stored screening record by id — the audit copy, retained ten years. Needs ARCNAUTICAL_API_KEY. | Read-only |
| get_usage | Live and test usage, remaining allowance, reset time, batch limits and monitor capacity for the configured key. | Read-only |
| 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 assessments a month are included with a self-serve key. | Changes data |
| 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 5,000 live screenings once (a one-time allowance). The same vessel asked again on the same day replays the stored record free. If the result is INCOMPLETE for identity, call again with vessel_name. | Changes data |
| 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. | Changes data |
