Brazilian Vehicles and Prices vs NHTSA

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.

NHTSA's vPIC (vehicle Product Information Catalog) API decodes VINs and looks up makes, models, and manufacturer/WMI data straight from the US government's own vehicle registry, with no signup required. A fresh live fetch of the vPIC operation index in this run lists 24 `/api/vehicles/*` operations and confirms none of them is a recall lookup — that's a separate NHTSA product (nhtsa.gov/recalls), not part of this API, correcting a prior run's summary. A live GET and OPTIONS preflight against vpic.nhtsa.dot.gov/api/vehicles/getallmakes both returned access-control-allow-origin: *, reconfirming cors "yes"; auth "None" and https were reconfirmed on the same calls. Responses are available in both JSON and XML via a format query parameter (XML is the live-confirmed default) — free, unlimited US government open data.
