This is a simple API client to pull vehicle data from the RDW (Rijksdienst Wegverkeer) OpenData API.
See: https://opendata.rdw.nl for more information.
Because this is Open Data provided by the government an API key is not needed.
$rdwApiClient = new \DOvereem\RDW\RDWOpenDataApiClient\RDWOpenDataApiClient;
$vehicleData = $rdwApiClient->getLicensedVehicleDataByLicensePlateNumber("AA-BB-CC");
