What the Valuation API returns

The API does not return a single magic number. It returns a price range, sample depth and market context so your team can understand where the estimate comes from.

Retail price range

Recommended net retail range for end-customer pricing, based on comparable European listings and adjusted for the selected specification.

Wholesale benchmark

Net wholesale reference range that helps compare B2B purchase price, auction bid level or stock acquisition cost against the retail market.

Explainable market context

Per-country medians, sample size, price distributions and sensitivity to mileage or registration year. Useful for pricing, sourcing and remarketing decisions.

Market depth and commercial setup

We only return valuations when there is enough comparable market data. This keeps the output more reliable and avoids giving false precision where the market sample is too thin.

Sample size rules

  • ✓ Minimum 20 comparable listings for any valuation.
  • ✓ Minimum 5 listings per country for local medians.
  • ✓ Minimum 10 listings in the primary country to use it as the base.
  • ✓ If local data is too thin, we fall back to the broader European distribution.

Commercial model

  • ✓ Fixed monthly packages or pay-per-call setup.
  • ✓ Separate pricing for valuation, validation and platform use.
  • ✓ Optional per-country, per-brand or high-volume configurations.
  • ✓ Can be used as API-only or built into the CarGenius auction platform.
