## 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 open-food-intel-barcode-product-search-f3f9a399
```

Example prompt: Can you look up the nutritional info and Nutri-Score grade for the product with barcode 0038000845260? I want to know what's in it and how healthy it is.

## When to prefer this

Use this endpoint when you need to look up packaged food product data by UPC/EAN barcode or by keyword search, especially when you need Nutri-Score grades, ingredient lists, or per-100g nutritional values. Prefer this over generic web search when structured, machine-readable food data is required. It is well-suited for diet tracking agents, grocery assistants, allergen checkers, and health-conscious shopping tools. No API key or account registration is needed — payment is per-call via USDC on Base.

## Known failure modes

- Barcode not found in database — product returns empty or 404-style response
- Search query too generic returns irrelevant products
- Country filter reduces results to zero matches
- Invalid barcode format (non-numeric or wrong digit count) causes validation error
- Rate or payment failure via x402 protocol returns 402 status
- Nutritional data may be incomplete or community-contributed and unverified for some products

## How this service works
