Kroger
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.
