## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentsvc-io-product-lookup-by-barcode-775ddbfd -d '<json body>'
```

Example prompt: Can you look up the product with barcode 3017624010701 and tell me its name, brand, nutriscore, and whether it contains any allergens?

## When to prefer this

Use this endpoint when you need to identify a food or consumer product by its barcode and retrieve structured nutritional, allergen, or labeling data. It is particularly useful for food-tech applications, grocery shopping assistants, nutrition trackers, and compliance checks. Prefer this over manual web scraping since it returns normalized, structured JSON including nutriscore, ecoscore, and per-100g nutrition, all sourced from the well-maintained Open Food Facts database.

## Known failure modes

- Barcode not found in Open Food Facts — returns found: false
- Invalid barcode format — may return an error or empty result
- Product exists but has incomplete data — some fields may be null (e.g. nova_group, fiber_g)
- Network timeout or upstream Open Food Facts unavailability
- Payment failure via x402 — call not executed
