Example prompt: Can you look up the product with barcode 737628064502 and tell me its name, brand, Nutri-Score, and nutrition facts per 100g?

## When to prefer this

Use this endpoint when you need to identify a food product and retrieve its nutritional profile, Nutri-Score, allergens, or ingredient list using a barcode or UPC. It is backed by Open Food Facts, the largest open food product database. Prefer this over generic web search when you need structured, machine-readable nutrition data tied to a specific product SKU.

## Known failure modes

- Barcode not found in Open Food Facts database — returns success: false or empty data
- Invalid or malformed barcode string — may return 404 or error response
- Product exists in database but has incomplete data (missing nutriscore, allergens, or image)
- Network or Vercel infrastructure timeout
