Example prompt: Can you look up the food product with barcode 3017620422003 and tell me its Nutri-Score, NOVA group, allergens, and nutritional values per 100g?

## When to prefer this

Use this endpoint when you need structured, multi-dimensional food product data (nutrition, health scores, allergens, sustainability) from a single barcode scan. Prefer it over a generic web search when you need machine-readable fields like Nutri-Score, NOVA, Eco-Score, and per-100g nutrients in a consistent schema. It is particularly suited for diet-tracking, allergen-detection, and sustainability-comparison workflows.

## Known failure modes

- Barcode not found in Open Food Facts database — returns null or empty product fields
- Invalid or malformed barcode string — may return no match
- Product exists but has incomplete data — some fields (e.g. fiber, nova) may be null
- Network or upstream Open Food Facts API unavailability — call may time out or return an error
