Vehicle Ownership API

Our benefits

Resolve an identity you already have a reason to check.

Five ways in

Query by VIN, by person with an address, by address alone, by phone, or by ZIP. One integration covers whichever identifier a case arrives with.

Integrate in minutes

One GET per entry point and a consistent record shape across all five. Copy the request from the panel below and swap in the identifier you hold.

People who know the graph

Enterprise onboarding, a documented response, and a team that will walk your permitted use and volume before you are switched on.

Priced per record

You pay for records returned, not requests made, and a lookup that resolves to nothing costs nothing. The count is the entries in the response.

For developers

One record shape, five ways in.

The panel on the right is a real request for a VIN and the owner record it returns. Scroll it to see the contact and demographic fields, then copy the request into your terminal and swap in whichever identifier your case holds.

Billed per record
A three-owner VIN bills three. A forty-record ZIP page bills forty. The count is the array length.
Watch ZIP and phone
ZIP is paginated to limit=100 and phone accepts up to 100 numbers per call, so both can bill large.
include only shapes output
The full record is fetched and billed as one base call whatever you pass; include just picks what is shown.

Fair billing

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.

Customer stories

Companies love building with CarsXE

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.
