Measured tools (7)

• check_vessel read-only

  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).

  Parameters:

  • imo (required) — string — Seven-digit IMO number of the vessel

  Hints: read-only yes · destructive not declared · idempotent yes · open-world yes

• find_port read-only

  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.

  Parameters:

  • query (required) — string — Port name, country, or LOCODE fragment, e.g. "rotterdam", "NLRTM", "Piraeus"
  • limit — integer — Maximum matches to return (default 5)

  Hints: read-only yes · destructive not declared · idempotent yes · open-world yes

• 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 free allowance of live screenings; get_usage reports what is left. 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.

  Parameters:

  • imo (required) — string — Seven-digit IMO number of the vessel
  • vessel_name — string — Only when a previous screen was INCOMPLETE for identity; a name you can confirm
  • include_vetting — boolean — false skips the vetting grade for a faster sanctions-only screen
  • customer_reference — string — Your own reference (order id, voyage id); echoed on the record

  Hints: read-only no · destructive not declared · idempotent yes · open-world yes

• 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.

  Parameters:

  • imos (required) — array — Up to 50 seven-digit IMO numbers
  • include_vetting — boolean — false skips the vetting grade for a faster sanctions-only screen

  Hints: read-only no · destructive not declared · idempotent yes · open-world yes

• get_screening read-only

  Fetch a stored screening record by id — the audit copy, retained ten years. Needs ARCNAUTICAL_API_KEY.

  Parameters:

  • id (required) — string — Screening id returned by screen_vessel or in a batch item

  Hints: read-only yes · destructive not declared · idempotent yes · open-world yes

• 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.

  Parameters:

  • origin (required) — string — Origin UN/LOCODE, e.g. NLRTM
  • destination (required) — string — Destination UN/LOCODE, e.g. CNSHA
  • dwt_tonnes — number — Deadweight in tonnes; used for chokepoint and draught constraints
  • speed_knots — number — Planned service speed, 8-25 knots; sets transit time through each risk area
  • vessel_type — string — Vessel class; changes which threat signals weigh most (default: general)
  • load_condition — string — laden or ballast; affects exposure on the transit
  • customer_reference — string — Your own reference (voyage id, fixture); echoed on the assessment

  Hints: read-only no · destructive not declared · idempotent yes · open-world yes

• get_usage read-only

  Live and test usage, remaining allowance, reset time, batch limits and monitor capacity for the configured key.

  Hints: read-only yes · destructive not declared · idempotent yes · open-world yes
