# vindex.vin
> The vehicle identity ladder — marque, lineage, vintage, guise, cut — issued from public evidence with every key ledgered, and every industry provider's IDs and trim, style, color, and option codes resolved through it.

Vindex owns the Atlas: a clean-room catalog of vehicle identity — the ladder every provider's catalog describes — issued, keyed, and counted, with each provider's identifiers mapped to it as sameAs edges and through it to each other. The ladder and its counts read free.

Motions: B2A
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.
