Brazilian Vehicles and Prices vs RevCarData

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.

RevCarData is a global Year-Make-Model-Trim vehicle database covering EU, US, and Asian markets, exposing 38 structured spec fields — MSRP, powertrain, dimensions, and EV/battery metrics — via a REST API and CSV export. A live GET against its real API host, api.revcardata.com/api/v1/vehicles, returned a 401 "Missing X-API-Key header" error carrying access-control-allow-origin echoing the request Origin — reconfirming auth "API Key" and cors "yes" — over HTTPS. Its site offers a free sign-up-and-get-a-key tier alongside paid plans for higher volume — freemium.
