Brazilian Vehicles and Prices vs Kelley Blue Book

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.

Kelley Blue Book's Cox Automotive-run API program (IDWS, Advertising Data, Instant Cash Offer, and Batch VIN) provides vehicle valuation, pricing, and configuration data behind an approval-gated API key, per developer.kbb.com's own access instructions. Its legacy Swagger doc-viewer content pages (/content/data/*.html) now 404 into the site's SPA shell — orphaned — but the surrounding portal, the key-request process, and Cox Automotive's successor developer platforms (developer.coxautoinc.com, coxautoinc.mashery.com) all remain live over HTTPS, confirming https true and that the program has moved rather than gone dead; cors could not be re-probed live since no public endpoint or key is available. Access requires Cox Automotive approval with no public self-serve signup — paid.
