Brazilian Vehicles and Prices vs Mercedes-Benz

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.

Mercedes-Benz's connected-vehicle API platform exposes telematics data, remote vehicle commands, a car configurator, and dealer-locator lookups behind an OAuth2 client-credentials/authorization-code flow — its own docs describe exchanging a Base64-encoded Client ID/Secret for a bearer token, correcting the stored auth from "API Key" to "OAuth". A live unauthenticated GET against the real api.mercedes-benz.com gateway returned no Access-Control-Allow-Origin header on any endpoint tested, reconfirming cors "no" — consistent with Mercedes-Benz's own documentation that the API doesn't support direct browser calls; https was reconfirmed. The platform offers a free sandbox/BYOCAR tier for testing against simulated and real vehicles, plus paid production tiers per API product — freemium.
