## 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 saylor-innovations-food-barcode-f09d014d
```

Example prompt: Can you look up the barcode 016000275782 and tell me the product name, brand, ingredients, allergens, and Nutri-Score?

## When to prefer this

Use this endpoint when you need to resolve a specific UPC or EAN barcode into packaged food metadata including nutritional information, allergens, Nutri-Score, Nova group, and Ecoscore. It is well-suited for grocery shopping assistants, diet-tracking agents, allergen-checking workflows, or any use case where a physical product barcode needs to be decoded into structured food data. Prefer this over scraping retailer pages when you need standardized nutrition fields in a machine-readable format.

## Known failure modes

- Barcode not found in database — returns {found: false} with null fields
- Malformed or non-numeric UPC/EAN string may result in error or not-found response
- Partial data — some fields (allergens, Ecoscore, Nova group) may be null if not in the source database
- Payment failure due to x402 protocol issues
- Rate limiting or upstream data source unavailability

## How this service works

Packaged food lookup by UPC or EAN barcode - name, brand, ingredients, allergens, Nutri-Score and nutrition facts

## Output

A JSON object with a `found` boolean indicating whether the barcode matched a record. If found, returns the product name, brand(s), quantity, image URL, ingredients text, allergen list, product categories, Nova processing group (1-4), Nutri-Score grade (a-e), Ecoscore grade, full nutrition facts per 100g (calories, fat, carbs, sugar, protein, salt, fiber, etc.), and the data source used.
