# VIN Price Check

> Lowest advertised price of record for a VIN (single or batch), with source and timeline.

**Price:** $0.50 per report. Runs inside Claude or ChatGPT (MCP), or as a shareable hosted web report. Pay per report, no subscription.

Returns the lowest ADVERTISED (listed) price of record for a VIN across the dealer websites Marketcheck crawls, with the source, dealer, date, and listing URL, plus the full advertised-price timeline and every distinct seller that advertised the VIN. Pass ONE VIN (vin) for the full single-VIN view, or MANY VINs (vins, comma or newline separated) for a batch summary table. All figures are advertised prices, never sale prices. Coverage is dealer websites (near-complete, built over years), not third-party aggregator marketplaces. This is the compliance-grade lookup behind the price-check API: it establishes the advertised price of record so the dealer can compare it against their own sale price. PRICING: $0.50 per VIN. A single VIN runs immediately. A BATCH is priced per VIN and requires cost confirmation: call first WITHOUT confirm_cost_usd to get a quote (this charges nothing), show the user the exact total, and only after they approve, call again with confirm_cost_usd set to the quoted total to run and charge the batch. Batches run up to 500 VINs at a time (a full lot in one run). Use when the user asks for the lowest or advertised price one or more VINs were advertised at, a VIN advertised-price history, or a neutral advertised price-of-record (advertised-vs-sold / FTC Act Section 5 / state advertising compliance). This is the ADVERTISED price, not market value (use Vehicle Valuation) and not a lot-wide compliance audit (use Pricing Compliance Report).

## Inputs

### Optional
- **vin** (e.g. `1HGCV2F38LA000777`): 17-character VIN for a single-VIN check. Provide this OR vins.
- **vins** (e.g. `1HGCV2F38LA000777, 4T3R6RFV7MU015349`): Multiple VINs for a batch check, comma or newline separated. Priced at $0.50 per VIN; requires cost confirmation via confirm_cost_usd. Up to 500 per batch.
- **confirm_cost_usd** (e.g. `4.9`): For batches only. After quoting the user the exact total and getting approval, call again with this set to the quoted total (e.g. 4.90). The batch runs and is charged only when this matches the server-computed total. Leave empty on the first (quote) call.
- **zip** (e.g. `60601`): Optional ZIP for location context. The check is VIN-keyed, so this is informational only.

## Data semantics

Every price is a **listed (asking) price**, not a transacted sale price. "Recently off-market" comps show a vehicle's last list price (a sold proxy). The ML "MarketCheck Price" predicts an optimal listing price, not a sale price.
