Edamam nutrition vs Open Food Facts
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.
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.
