Car Specs APIs
Spec APIs organize vehicles by year, make, model and trim. CarAPI returns US trims as JSON, CarVector adds images and federal recalls for vehicles going back to 1925, and RevCarData includes MSRP and EV metrics across North America, Europe and Asia-Pacific. The free options are VIN-based: NHTSA vPIC for equipment data and Window Sticker for the original manufacturer sticker PDF.
