## How to call it through Zero

```sh
zero fetch --capability food-product-by-barcode-f62ff284
```

Example prompt: Can you look up the food product with barcode 3017620422003 and tell me its ingredients, allergens, and Nutri-Score?

## When to prefer this

Use this endpoint when you need structured food product data keyed by a physical barcode scan, particularly for nutrition apps, shopping assistants, or allergy screening tools. It's ideal when you have the barcode number and need rich data including Nutri-Score, NOVA group, Eco-Score, and allergens in a single call. Prefer this over manual web scraping or general search when you want machine-readable nutritional facts tied to a specific product SKU.

## Known failure modes

- Barcode not found in Open Food Facts database — product may be regional or unlisted
- Invalid barcode format returns an error — must be EAN-13, EAN-8, or UPC
- Incomplete product data if Open Food Facts entry is community-contributed and partially filled
- Service downtime on the Render-hosted endpoint causing HTTP errors
- Rate limits or payment failures returning 402 responses

## How this service works
