Get an ML-based market value estimate for a used vehicle by VIN using the MarketCheck Price API, separate from MarketCheck's inventory feeds
domain: marketcheck.com · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Call GET https://api.marketcheck.com/v2/predict/car/us/marketcheck_price with your api_key as a query parameter
Supply the required vin, miles, and dealer_type (franchise or independent) parameters
Supply either a zip code, or a city plus state, to localize the valuation
Optionally pass is_certified if the vehicle is CPO, since certification affects the predicted value
If comparable listings or a full NeoVIN decode are needed alongside the valuation, use the /comparables or /comparables/decode path suffixes, which require higher-tier plan access
Known gotchas
This valuation endpoint is architecturally separate from both MarketCheck's dealer inventory syndication feeds and its basic/NeoVIN VIN decoder — one subscription tier may not include all three
dealer_type is a required enum (franchise|independent) with no 'unknown' option — you must classify the selling context before calling the endpoint
The /comparables and /comparables/decode extensions are gated to Premium/Premium Plus tiers respectively — a lower-tier key will fail on those paths even though the base valuation call succeeds
