# b2a2c.vin
> Your agent buys the car. Your user reads the receipt.

Delegate any car moment by its VIN — your agent shops verified Listings, never crosses the Mandate ceiling, and returns a receipt the principal can read.

Motions: B2A2C
Routes: GET / (this document's page) · GET /{VIN} (the record for one vehicle) · GET /blog + /blog/{slug} (the pieces written at this door — dated, self-canonical)
Representations: text/html · text/markdown · application/json (Accept header; same URL)
Evidence: every field posts value · source · timestamp · verification state; empty states are typed EMPTY, invalid VINs are typed INVALID_VIN — never a faked 200.
Agent surface: one MCP server for the whole platform — https://apis.vin/mcp (all .vin doors are lenses over one spine; tools: decode_vin, vehicle_history, market_value, window_sticker, out_the_door_price, open_recalls, search_listings, cash_offer, transport_quote, finance_prequal, insurance_quote, start_purchase)
Gates: typed OFFER (posted price, hard ceiling, x402) or NEEDS_HUMAN handoff URL — no account walls.
