## 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 codepulse-barcode-reader-132ec505 -d '<json body>'
```

Example prompt: Can you read the barcode in this image and tell me what the value and format are? Here's the image URL: https://example.com/product-barcode.jpg

## When to prefer this

Use this endpoint when you have an image URL containing a barcode and need to extract the encoded value and format without maintaining your own barcode-scanning infrastructure. It handles multiple barcode standards (EAN, UPC, QR, etc.) and returns confidence scoring. At $0.02 per call with no API key required, it is ideal for on-demand or low-volume barcode reading tasks in agent workflows.

## Known failure modes

- Image URL is inaccessible or returns a non-image — no barcode found result
- Image contains no detectable barcode — returns found: false
- Barcode is too blurry or partially obscured — low confidence or not found
- Unsupported barcode format — supported: false in response
- Invalid or malformed image URL — request error

## How this service works

Decodes EAN, UPC, or ISBN barcode values from an image URL.

## Output

Returns a JSON object with: 'found' (boolean indicating if a barcode was detected), 'format' (barcode standard such as EAN_13, UPC_A, QR_CODE, etc.), 'barcode' (the decoded string value), 'confidence' (high/medium/low quality indicator), 'warnings' (any issues encountered), 'supported' (whether the format is supported), and a disclaimer about informational use only.
