Market Data Tools

Raw MarketCheck data, priced per call.

Reports give you the synthesized read. These six tools give your AI assistant the raw data underneath, billed per call from the same balance. Ask directly ("show me Rogue listings under $20k near 84070", "pull the listing history on this VIN") or as a follow-up to any report: when a Stocking Guide names a hot nameplate or a Full Market Capture run flags a stalled unit, the assistant can fetch the actual listings, the VIN's history, or a price prediction without re-running a report.

All data tools

Active listings search

40M+ live dealer listings, 100+ filters. "What Rogues are listed under $20k near me?"

$0.01 per call

Recently sold search

Listings that left the market in the last 90 days, with counts and medians. A sold proxy at last list price, against 410M sold or off-market listings.

The foundation

Every insight sits on the largest live automotive dataset in the U.S.

We've been continuously crawling, decoding, and normalizing every dealer listing in North America since 2014. The result is a market intelligence layer that other valuation tools can only approximate, and every MarketCheck report cites it directly.

How it works

Three steps. No code.

01

Add MarketCheck to Claude or ChatGPT

One link, one click, paste it into Claude or ChatGPT. Takes about 30 seconds. Or open one of our reports and click Add to Claude.

02

Add starter credits

Your balance is real money, not abstract credits. Reports start at $0.99 each (most VIN reports run $0.99 to $1.99), with a $25 starter minimum. Auto top-up keeps you running, and unused balance is fully refundable.

03

Ask Claude or ChatGPT a question

"What's this Camry worth?" "Scan my lot for under-priced cars." "Local market for SUVs in 60601?" Your assistant pulls the report, narrates it, and charges your credits.
