Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Protected Resource Metadata +5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified)

4 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Developer Ergonomics scores 49.4 — up to +10.1 composite points
Contract Governance scores 22.0 — up to +9.4 composite points
Contract Quality scores 65.4 — up to +8.7 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/arcnautical-com/apis.yml: open an issue on github.com/api-evangelist/arcnautical-com to ask a question or point us at an artifact you publish.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

APIs 12

Individual APIs this provider publishes, each with its own machine-readable definition.

ArcNautical Account API

ArcNautical Cargo screening API

Commodity, origin and discharge screening against sanctions programmes and export controls.

ArcNautical Corridor monitors API

Standing route-risk subscriptions that deliver an event when a corridor score changes.

ArcNautical Crew placement API

For Indian crewing agencies (RPSL holders): may Indian seafarers be placed on this ship under DGS Order 08 and DGMA Order 22 of 2026? A dated, hash-verifiable record per check, ...

ArcNautical Exports API

One file for a whole resource — screenings, cargo screenings, access log — instead of a paging loop.

ArcNautical Fleets API

Named sets of hulls with an exposure roll-up and a change feed, for asking what moved since a cursor instead of re-screening the whole book.

ArcNautical Port lookup API

Unauthenticated UN/LOCODE resolution. Routes are addressed by LOCODE, so this is how a caller turns a port name into one. Every LOCODE validation error points here.

ArcNautical Public vessel check API

Unauthenticated hull screening. IP rate-limited, cached, and not retained against a customer. Requires no key and no account — this is the endpoint the documentation leads with.

ArcNautical Vessel monitors API

A standing subscription per hull. We re-screen on our schedule and deliver an event only when the verdict moves, so a book need not be re-screened to stay current.

ArcNautical Vessel screening API

The authenticated screening record for one hull, or a batch of up to 50: every sanctions match with its source list and confidence class, ownership opacity, the graded vetting f...

ArcNautical Voyage assessments API

Synchronous and batch route risk scoring by UN/LOCODE, retained for audit.

ArcNautical Webhooks API

HMAC-SHA256 signed delivery of every event type, with delivery history and redelivery.
