The gate is a 402 OFFER — the price and a hard ceiling on the wire, with a durable intent that executes on settlement. Never a wall, never "contact sales". Price: not posted — see /pricing.

Door — aggregator.vin serves this noun on its two routes: / (the landing) · /19XFC1F72LE208310 (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.
