Open Food Facts

Overview

Open Food Facts is the world’s largest free, open food database — 3M+ products with ingredients, allergens, nutrition facts, additives, and Nutri-Score. Keyless and free (verified live), it’s the go-to API for nutrition apps, barcode scanners, and food transparency projects.

Rate Limits & Notes

• Free, open data (ODbL) — no key; be polite (the API asks for a descriptive User-Agent).
• The v2 API endpoint is api/v2/product/{barcode}.json — barcodes are EAN/UPC.
• Rich fields: ingredients_text, nutriments (per-100g values), nutriscore_grade, nova_group (processing), additives_tags, allergens_tags.
• Search uses the legacy CGI endpoint (/cgi/search.pl?search_terms=...&json=1).
• Bulk data dumps are also available for offline analysis.
