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.

Quick reference

  • No authentication required. The endpoint is public — no credentials or headers needed.
  • Filter with JSON:API bracket syntax: ?filter[make]=TESLA, ?filter[region]=US, ?filter[powertrainType]=PHEV. Flat parameters (e.g. ?make=TESLA) are silently ignored.
  • Returns the full matched dataset in a single response. Pagination parameters are not honored — cache results locally and refresh daily.
See Compatible Vehicles for the full parameter list, response schema, and examples.
