Kroger vs Open Food Facts
Kroger's public API exposes product search, pricing, and store-locator data across its US supermarket banners for registered developer applications using an OAuth client-credentials token. A live GET against the real gateway, api.kroger.com, returned a genuine 401 'access_token is missing' JSON error while carrying an echoed Access-Control-Allow-Origin header, resolving cors unknown -> yes and reconfirming API Key auth in the same probe.
Open Food Facts is a crowdsourced, open database of food products worldwide, covering ingredients, nutrition facts, allergens, and Nutri-Score/Eco-Score ratings, with full bulk exports available alongside the live API. A live GET against the real gateway, world.openfoodfacts.org, returned a genuine product record while carrying Access-Control-Allow-Origin: *, resolving cors unknown -> yes; auth None was reconfirmed by the same keyless 200.
