About

Open Food Facts is a community-contributed food-product database with a barcode lookup API. Reads need no credentials but require an identifying User-Agent and obey rate limits. Data can be incomplete or inaccurate; ODbL database and separate image licenses apply.

Show ingredients and listed allergens for a packaged food
Filter food products by nutrient fields with the structured search API
