## 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 northline-product-barcode-lookup-sample-411aff8b -d '<json body>'
```

Example prompt: Can you look up what product this barcode corresponds to — 012345678905 — and tell me the product name, brand, and category?

## When to prefer this

Choose this endpoint when you need lightweight, no-account-required barcode-to-product lookups and are willing to pay micro-transactions per call via USDC on Base. Ideal for agents that need ad-hoc product identification without committing to a subscription or API key registration. Best for low-to-moderate volume lookups where per-call cost of $0.008 USDC is acceptable.

## Known failure modes

- Barcode not found in database — returns empty or 404-style response
- Invalid barcode format — returns validation error
- Payment failure via x402 — request rejected before processing
- Server unavailable — IP-based host may have reliability issues
- Sample endpoint may only support a limited set of demo barcodes
