No input — this capability takes no request body.

Door — aggregator.vin serves this noun on its two routes: / (the landing) · /KL4CJASBXJB647018 (the VIN lens).

Try it — sandbox: every call answers a deterministic, provenance-labeled simulated payload ({ environment, simulated } in the body). Force any documented outcome with the magic triggers. Going live is a connect, never a ballot: submit the credential at integrates.vin (dealer systems) or connects.vin (consumer accounts) — submissions enter the activation queue and rank live rollout.

Emits — Ownership.failed@1 · Ownership.verified@1 · Vehicle.ownershipVerified@1.

import { ownership } from 'apis.vin'

// the gate law is in the type system: Answer<T> = Ok | Empty | Blocked | Offer
const answer = await ownership.verify()

curl -X POST https://apis.vin/ownerships/verify \
  -H 'content-type: application/json' \
  -d '{}'

Receipt — the sandbox wire answered the request above with this exact body at build time. Captured by the receipts runner (timestamped, provenance in the payload), never authored; it re-executes only when this descriptor changes.
