## 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 ishob-product-barcode-lookup-f5bd9089
```

Example prompt: Can you look up the barcode 3017620422003 and tell me what product it is, including its brand, Nutri-Score, and any labels?

## When to prefer this

Choose this endpoint when you need to identify a physical product or book from a scanned or typed barcode number, validate barcode integrity, convert between barcode formats, or enrich product data with nutrition, brand, or publishing metadata from open databases — especially for food, cosmetics, pet food, or books.

## Known failure modes

- Invalid barcode length or format returns validation error with details
- Barcode not found in open databases returns empty product fields
- Wrong check digit reported with corrected digit rather than error
- Network timeout fetching from Open Food Facts or Open Library
- Non-barcode string input (e.g. letters) rejected as invalid

## How this service works

Look up a product barcode number: identify and validate EAN-13, EAN-8, UPC-A, UPC-E, GTIN-14, ISBN-13/10, ISSN and ISMN codes (wrong check digits are reported with the correct digit), convert between forms (GTIN-14, EAN-13, UPC-A, ISBN-10 <-> 13) and decode the GS1 prefix. Then fetch product data from open databases: name, brand, quantity, categories, image, labels, Nutri-Score (food, cosmetics, pet food via Open Food Facts) or title, authors, publisher and cover (books via Open Library).

## Output

Returns validated barcode details (type, check digit status, correct check digit if wrong), converted equivalent forms (GTIN-14, EAN-13, UPC-A, ISBN-10/13), decoded GS1 prefix, and when lookup is enabled: product name, brand, quantity, categories, image URL, labels, Nutri-Score (for food/cosmetics/pet food) or book title, authors, publisher, and cover image URL.
