In one sentence

Dealer Agent Protocol is an open, read-only contract that lets AI agents discover dealer-published vehicles, verify availability, and explain retail pricing with source, freshness, authority, and uncertainty.

Version 0.1 scope

The first release defines one focused retail read: who is selling the vehicle, which vehicles are published, whether a specific vehicle is available, and how its price and offers should be explained.

Core retail fact	What the agent learns
Dealer and rooftop identity	Who is publishing the inventory and retail offer.
Published inventory and vehicle facts	Which exact vehicles are being presented for sale.
Authoritative availability	Whether a specific vehicle is currently available, according to the designated authority.
Pricing and required charges	Which amounts apply to every buyer in the disclosed context.
Discount and incentive conditions	Which offers may apply and what must be true for eligibility.
Provenance and freshness	Where each fact came from and how recently it was observed.
