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

    Follow the API lookup guide to create a key. Sandbox keys return sample valuations for the test registrations.

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.
