## How to call it through Zero

```sh
zero fetch --capability api-strale-io-7aed2dfb
```

Example prompt: Can you look up the product info for barcode 049000028911 — I want to know the name, brand, and nutrition facts?

## When to prefer this

Use this endpoint when you need to identify a physical product by its UPC or EAN barcode, especially for food and grocery items where nutrition data is valuable. Prefer this over manual product databases when you need aggregated data from both Open Food Facts and UPC ItemDB in a single call.

## Known failure modes

- Barcode not found in either database — returns empty or null product data
- Invalid barcode format — schema requires a barcode string query parameter
- Payment not completed (x402 protocol) — returns 402 status before data is delivered
- Upstream Open Food Facts or UPC ItemDB unavailable — may return partial or error response
