Compatibility API overview

Vehicle compatibility data by make, model, region, and powertrain, updated daily from the Smartcar platform.

The Compatibility API tells you which signals and commands each vehicle supports. The data comes from real connections on the Smartcar platform and updates daily.

Filtering and caching

• Filter by powertrain type (BEV, PHEV, ICE, HEV), region (US, Canada, Europe), or manufacturer
• Cache results locally and refresh daily since the dataset changes each day
