## 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 nexusapi-qr-code-decoder-8590e409 -d '<json body>'
```

Example prompt: Can you decode this QR code for me and tell me what text or URL it contains? Here's the image: https://example.com/qrcode.png

## When to prefer this

Use this endpoint when you need to programmatically extract the data embedded in a QR code image without manually scanning it with a phone. Ideal for automation pipelines that encounter QR codes in documents, product images, or web pages and need to resolve the encoded content.

## Known failure modes

- Image URL is inaccessible or returns a 404 — cannot fetch QR code
- Input image does not contain a detectable QR code — returns an error or empty result
- Image quality is too low or QR code is partially obscured — decoding fails
- Unsupported image format — service cannot parse the image type
- Network timeout when fetching remote image URL

## How this service works

## Output

Returns the decoded content embedded in the QR code, which may include a URL, plain text, contact information, Wi-Fi credentials, or any other data that was encoded into the QR code image.
