# By Region and Make

> Compatibility will vary by model, year, and trim. This API is for reference purposes only and it showcases vehicle makes and models that may be compatible with Smartcar and it does not guarantee that a specific vehicle will be compatible.

<Warning>
  **This endpoint is deprecated.** Please use the new [Compatible Vehicles](/api-reference/compatible-vehicles) page for up-to-date, signal-based compatibility data that is dynamically updated from the Smartcar platform.
</Warning>

Compatibility by region and make allows developers to query the latest version of our Compatibility Matrix based on region, engine type, make, and permission.
