Open Food Facts
Open, crowdsourced database of millions of packaged food products with nutrition facts, ingredients, allergens, and Nutri-Score by barcode; no API key for reads.
Open Food Facts is a Wikipedia-style, fully open (ODbL-licensed) database of food products from around the world. Read operations need no API key; you look up any product by its barcode (EAN/UPC) and get product name, brands, ingredients, allergens, additives, Nutri-Score, NOVA group, Eco-Score, full nutriment values per 100g, categories, labels, and packaging data. A search API lets you query and filter products by category, brand, label, nutrition grade, and more. Perfect for nutrition-tracking skills, barcode-scanning automations, diet/allergen filtering, and ingredient analysis.
