Brazilian Vehicles and Prices vs Smartcar

Brazilian Vehicles and Prices (the FIPE API) wraps Brazil's official Fundação Instituto de Pesquisas Econômicas price table for cars, motorcycles, and trucks, returning brand, model, year, and the government reference resale price as JSON. A live GET and OPTIONS preflight against its real API host, parallelum.com.br/fipe/api/v1/carros/marcas, both returned access-control-allow-origin: *, resolving the stored "no" cors to "yes"; no key was required, reconfirming auth "None" over HTTPS. The service is capped at 500 free unauthenticated requests/day, 1,000/day with a free registered token, or unlimited via a paid plan at fipe.online — freemium.

Smartcar's Vehicle API lets apps lock/unlock vehicles and read odometer, location, and other telematics data from most late-model cars through a single OAuth2 integration across dozens of automaker backends. A live unauthenticated GET and OPTIONS preflight against api.smartcar.com/v2.0/vehicles both returned no Access-Control-Allow-Origin header — resolving the stored "yes" cors to "no", consistent with Smartcar's own docs, which say API calls must be made from a backend, never a browser; auth "OAuth" and https were reconfirmed via a 401 AUTHENTICATION error. Its pricing page offers a Free plan (1 connected vehicle, no credit card) alongside paid Growth/Enterprise tiers — freemium.
