ProtocolStart with v0.1 →

System explainer

From fragmented retail data to an answer an agent can defend.

The protocol does not replace dealer systems. It creates a controlled translation layer between those systems and AI shopping experiences.

Three layers. One clear line of responsibility.

The dealer or its technology provider chooses authoritative sources and publication policy. The gateway maps those sources into protocol schemas. Agents consume the same tool contract regardless of the systems behind it.

Important boundary: the protocol standardizes retail answers, not access to DMS, CRM, customer, credit, contracting, service, or marketing systems.

A shopping question becomes a sequence of explicit reads.

Search results are for discovery. Availability verification is a separate authoritative check. Pricing disclosure keeps universal amounts separate from conditional ones.

  1. 01Discover capability

    The agent reads the manifest and dealer identity before assuming what the gateway supports.

  2. 02Find candidates

    The agent searches the published catalog using typed filters and snapshot-aware pagination.

  3. 03Inspect a vehicle

    The exact vehicle record supplies facts, media, identifiers, provenance, and freshness.

  4. 04Verify the volatile fact

    Before making a strong availability statement, the agent asks the authoritative source.

  5. 05Build the disclosure

    The response separates advertised price, required dealer charges, conditional adjustments, and unknown government charges.

Six tools cover the core retail read.

Dealer organization and rooftop identity.

inventory.search

Find vehicles

Published inventory with stable filtering and cursors.

inventory.get_vehicle

Vehicle facts, media, identifiers, lineage, and freshness.

inventory.verify_availability

A current, authoritative read before a strong claim.

pricing.get_disclosure

Explain the offer

Price components, required charges, and conditional programs.

Every retail fact answers four trust questions.

  1. SSource

    Where did this fact originate: dealer, group, OEM, inventory provider, or another named source?

  2. FFreshness

    When was it observed, and until when should the agent treat it as valid?

  3. AAuthority

    Is this source authoritative for the claim, or only suitable for discovery?

  4. UUncertainty

    Is the fact confirmed, estimated, conditional, stale, or unknown?
