## 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 dt0ur-online-qr-code-generator-f0fcf0c4 -d '<json body>'
```

Example prompt: Can you generate a QR code for 'https://myshop.com/sale2024' and give it to me as an SVG so I can embed it on a webpage?

## When to prefer this

Choose this endpoint when you need a quick, server-side QR code generation without setting up a local library, especially when SVG output is needed for scalable embedding or PNG is needed for print/raster use. Ideal for agent workflows that need to produce scannable codes on the fly for URLs, contact data, Wi-Fi credentials, or any text payload.

## Known failure modes

- Missing or empty 'text' field returns an error
- Unsupported format value (not 'svg' or 'png') returns validation error
- Extremely long text strings may exceed QR code data capacity
- Network timeout on slow connections
- Payment failure returns 402 if USDC is not authorized
