Four components per value
Vehicle Market Value API
Price a vehicle from its VIN, mileage and state.
- Wholesale and retail values per condition
- Excellent, clean, average and rough tiers
- Base, mileage, options and regional parts
- Identity: year, make, model, series, style
Our benefits
A number your system can defend.
The value shows its work
Each bucket returns a base value plus what mileage, options and region moved it, so you can show a customer why the number is the number.
Integrate in minutes
Only the VIN is required. Copy the request from the panel below, add mileage and state when you have them, and the first valuation runs in minutes.
People who know valuations
A free sandbox, a documented response, and support that can tell you how a market behaves before you wire the number into an offer screen.
Prices one car, not a model
Mileage, state and condition go in with the VIN, so the estimate is for that specific vehicle in that market rather than a national average.
For developers
Every value, broken into four parts.
The panel on the right is a real request for VIN WBAFR7C57CC811956 at 50,000 miles in California, and the response it returns. Scroll it to see how each value breaks apart, then copy the request and swap in a VIN and mileage of your own.
- Each value breaks down
- A bucket returns its base value plus separate mileage, add_deduct and regional adjustments.
- Every field is optional
- A missing bucket means the provider returned no valuation for this VIN or market, not that it is zero.
- Call /v2/marketvalue
- That is the current route and the shape these fields come from. An older v1 route returns different buckets.

No data, no charge
A lookup we cannot resolve comes back as a 404 and costs you nothing. You are billed only when the API returns data.

Strongest in the US market
Robust international support
Valuations are strongest in the United States. The endpoint takes a country parameter, and coverage outside that market is thinner.

How teams build on CarsXE vehicle data.
“
CarsXE offers MotorTango's customers accurate and reliable vehicle data across many makes and models. Their VIN decoder and specs API are second to none.
Andy Liakos
CTO, MotorTango
“
The API is super easy to work with...it's a damn good API. And trust me, I deal with a lot of third parties and you're the creme de la creme. It's great. Documentation is sound, the result sets are sound. I have nothing to say but, man, it's too easy to work with.
Alan Deitch
Senior Engineering Leader, SpotHero
“
When a customer calls a dealership, we know they have an open recall instantly. That changes what the call is worth. Our agents book the recall alongside whatever the customer originally called about, and the dealer captures service work that used to walk out the door unnoticed. CarsXE's recall data is what makes that possible on every call, at every rooftop we run.
Samee Khan
Founder & CEO, PAM
“
With their VIN decoder and images, we can accurately document what's needed to perform repairs and ADAS calibrations, and we do it much more efficiently — saving dozens of minutes on every single repair. The result is consistent, reliable service at scale for all of our customers, backed by data we trust. CarsXE has become a critical part of our workflow and our ability to grow.
