Edamam nutrition vs Untappd

Edamam's Nutrition Analysis API parses a free-text ingredient line and returns calories, macro/micronutrients, and diet and health labels for that food or recipe, aimed at meal-tracking apps. A live GET against the real gateway, api.edamam.com, returned a genuine 401 'Unauthorized app_id' JSON error while carrying an echoed Access-Control-Allow-Origin header, resolving cors unknown -> yes and reconfirming API Key auth (an app ID and key pair) in the same probe.

Untappd's public API exposes its social beer check-in platform — beer and brewery details, user check-ins, and venue activity — for applications registered through its OAuth developer program, free and rate-limited to 100 calls/hour per key. A live GET against the real gateway, api.untappd.com, returned a genuine 'missing client_secret/client_id' JSON error while carrying Access-Control-Allow-Origin: *, resolving cors unknown -> yes and reconfirming OAuth auth in the same probe.
