What is the Open Food Facts API?

Open Food Facts is a free, open-data API covering over three million food products worldwide. Look up any product by barcode to get ingredients, nutrition facts, allergens, Nutri-Score and eco-score, with no API key.

Open Food Facts is a collaborative open-data project, effectively Wikipedia for food products. Scan a barcode, get back the full ingredient list, nutrition table per 100g, allergen warnings and computed scores — all as open data with no commercial tier.

Because the data is crowd-sourced, completeness varies by product and region. Coverage is excellent across Europe and steadily improving elsewhere, but you should always code defensively: any given field may be absent for a given product.

Common errors and how to fix them

status: 0

Barcode not in the database.

Fix: Coverage is crowd-sourced and incomplete — handle misses gracefully and consider letting users contribute the product.

Missing nutriment fields

Not every product has complete data.

Fix: Never assume a field exists; check before reading, especially for allergens and scores.

Very large response

Full product records are big.

Fix: Use the `fields` parameter to request only what you render.

Open Food Facts API — frequently asked questions

Is there a free barcode API for food products?

Yes. Open Food Facts covers over three million products worldwide with no API key, returning ingredients, nutrition, allergens and Nutri-Score by barcode.

How complete is the data?

It varies. The database is crowd-sourced, so coverage is strongest in Europe and thinner elsewhere, and individual fields may be missing for any product. Always code defensively.

What is Nutri-Score?

A front-of-pack nutritional rating from A (best) to E (worst) used across much of Europe, computed from the product's nutritional composition. Open Food Facts exposes it as `nutriscore_grade`.

Can I use Open Food Facts commercially?

Yes, the data is under the Open Database Licence, which permits commercial use provided you attribute the source and share adaptations under the same licence.
