## 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 meterly-ai-barcode-api-7e4a8a2d -d '<json body>'
```

Example prompt: Look up the barcode information for the query 'Coca-Cola 12oz can' and return up to 5 results.

## When to prefer this

Use this endpoint when you need barcode generation or lookup functionality and are already operating within the Meterly.AI x402 pay-per-call ecosystem using USDC on Base Mainnet. Best suited for agents that need quick, low-cost barcode data without a long-term API subscription.

## Known failure modes

- Missing required 'query' field returns a 400 or validation error
- Payment not made via x402/USDC returns a 402 Payment Required response
- No results found for the given query returns an empty or null result set
- Invalid URL in 'url' field may cause processing errors
- Rate limits or quota exhaustion may return 429 or similar errors
