How to get vehicle valuations and market data through the API

Updated 3 September 2026 · 1 min read · by DealerPricing

POST a registration and mileage to /api/v1/vehicle/valuation to receive trade, retail and part-exchange values derived from live UK dealer listings. Pair it with /api/v1/market/active for comparable cars for sale, /api/v1/market/sold for recent sale prices and /api/v1/market/insights for days to sell and supply. Valuation calls cost £0.16 to £0.25 each.

Step by step

  1. Get a key and test in the sandbox

Frequently asked questions

Are the API valuations the same as the dashboard?

Yes. They use the same live listing index and models, so a website widget and the desk valuation agree.

Can I show valuations on my own website?

Yes. Typical uses are part-exchange enquiry forms, stock pricing tools and customer-facing "value my car" pages. Cache results for a few hours to keep call costs down.

What does a valuation call cost?

£0.25 on pay as you go, £0.21 on Starter, £0.19 on Pro and £0.16 on Enterprise. Market listing calls are £0.05 to £0.15.
