Vehicle DNA
One VIN. One record. Only your facts.
Each VIN in your daily feed becomes one structured record built for AI assistants and linked to your vehicle page.
The record
Six verified facts per VIN.
- Identity: VIN, stock number, year, make, model, and trim
- Price: Exact asking price shown on your vehicle page
- Equipment: Options and features in your listing’s words
- Photos: Images tied to that specific VIN
- Availability: Present in today’s feed, or retired
- Destination: Tagged vehicle-page URL on your domain

Where the record goes
Published four ways for language models.
01 · PAGES
Machine-readable vehicle pages
Clean per-VIN pages a language model can read without parsing site chrome.
02 · SCHEMA
Structured data
Year, trim, equipment, and price explicitly labelled rather than inferred.
03 · INDEX
/llms.txt
A plain-text index at the standard path pointing models to your ready vehicles.
04 · ENDPOINTS
Assistant connections
MCP and actions endpoints that return your tagged vehicle-page link on match.
On every feed run
Rebuilt daily. Retired when sold.
- Read feed: Scheduled feed URL or export file ingested each morning.
- Run 3 checks: Identity, price, and VDP URL verified per VIN.
- Update DNA: Price or photo changes update the record on the same run.
- Retire sold cars: VINs that leave the feed leave the answer path.
