GET
This endpoint is deprecated and will be removed on September 15, 2026. After that date, requests return 410 Gone.Compatibility by VIN infers compatibility from a VIN’s make and model and does not guarantee that a specific vehicle is compatible. The most reliable way to confirm compatibility is to connect the vehicle through Smartcar Connect — Smartcar then reports exactly which signals and commands that vehicle supports, based on real activity on the platform.To browse coverage across makes and regions, see Compatible Vehicles, which reflects vehicles already active on the platform.
Compatibility by VIN allows developers to determine if a specific vehicle could be compatible with Smartcar. A vehicle is capable of a given feature if:
  1. The vehicle supports the feature (e.g., a Ford Escape supports /fuel but a Mustang Mach-e does not)
  2. Smartcar supports the feature for the vehicle’s make
This endpoint only supports checking capabilities for vehicles sold in the United States. It does not support checking capabilities for VINs in Canada and Europe.

Request

Headers
​
string
default:"Basic "
required
The HTTP Authorization header using the Basic authentication scheme.To construct the Authorization header value:
  1. Join your client_id and client_secret with a single colon (:).
  2. Base64-encode the resulting string: base64({client_id}:{client_secret})
  3. Prepend Basic (with a trailing space) to the encoded string.
Your final authorization header value should look like this:Basic bXktY2xpZW50LWlkOm15LWNsaWVudC1zZWNyZXQ=
Parameters
​
string

A space-separated list of permissions.
​

Response

​
boolean
true if the vehicle is likely compatible, false otherwise.
​
string | null
One of the reasons described below if compatible is false, null otherwise
​
array
An array containing capability objects for the set of endpoints that the provided scope value can provide authorization for. This array will be empty if compatible is false.
A vehicle’s compatibility depends on many factors such as its make, model, model year, trim, etc. The API optimizes returning false positives.
