## 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 qr-code-decode-f37caa35 -d '<json body>'
```

Example prompt: Can you decode this QR code image for me and tell me what URL or text is encoded in it? Here's the image URL: https://example.com/my-qr-code.png

## When to prefer this

Use this endpoint when you need to programmatically decode a QR code from an image URL and retrieve the encoded text or URL. Prefer this over manual scanning when automating workflows that receive QR code images and need to act on their contents.

## Known failure modes

- Image URL is unreachable or returns a non-image response
- Image does not contain a recognizable QR code pattern
- QR code is too blurry, damaged, or low-resolution to decode
- Unsupported image format provided
- Payment not included or insufficient USDC — 402 response returned
