## 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 toolsmith-barcode-product-lookup-240c59eb
```

Example prompt: What product is barcode 3017620422003? I need the brand, Nutri-Score, NOVA group, allergens, and sugar content per 100g.

## When to prefer this

Use this endpoint when you need structured product metadata — nutrition, allergens, safety scores, packaging — from a physical EAN/UPC barcode without setting up an account or API key. Ideal for food-safety agents, diet trackers, sustainability tools, or compliance checks that need pay-per-call economics with no subscription overhead.

## Known failure modes

- Barcode not found in database — returns empty or null product fields
- Invalid EAN format (non-numeric or wrong digit count) — schema validation error
- Product exists but has incomplete data — some fields (e.g. recalls, packaging) may be empty arrays
- Payment failure via x402 — call not executed if USDC balance insufficient

## How this service works

Full product truth from an EAN/UPC barcode: name, brand, quantity, categories, complete ingredients, allergens, additives, nutrition per 100g, Nutri-Score / NOVA / Eco-Score, packaging materials with recycling info, plus any linked CPSC or FDA recall for the same barcode. Covers food, general products and cosmetics (Open Food/Products/Beauty Facts). JSON response. $0.02 USDC per call, pay via x402, no API key.

## Output

A JSON object with the product name, brand, allergen list, NOVA group (processing level 1-4), Nutri-Score letter (a-e), packaging materials and recycling guidance, nutrition facts per 100g (energy in kcal, sugars, etc.), and any active recalls.
