## 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 datavault-qr-code-generator-d827c851 -d '<json body>'
```

Example prompt: Can you generate a QR code for 'https://myshop.example.com' at 300 pixels in PNG format?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call QR code generated from arbitrary text or URLs without managing your own QR library or infrastructure. Ideal for agents automating content creation or publishing workflows where QR codes are needed on demand.

## Known failure modes

- Missing required 'text' field returns validation error
- Invalid size value (non-integer or negative) causes bad request
- Unsupported format string results in error response
- Empty text string may produce unusable QR code
- Payment failure (insufficient USDC) blocks the request
