## 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 api-x402node-dev-33ee3706
```

Example prompt: Generate a QR code for https://myshop.example.com/menu — I need it as a base64 PNG image I can embed in a webpage.

## When to prefer this

Use this endpoint when you need to programmatically generate a QR code and receive it as a base64 PNG data URL — ideal for embedding directly into HTML, PDFs, or emails without needing a separate image hosting step. Prefer this over redirect-based QR services when you need the raw image data returned inline.

## Known failure modes

- Missing or empty text input returns an error
- Extremely long input strings may exceed QR code data capacity
- Network timeout if the service is temporarily unavailable
- Invalid request body format returns a 400-style error
- Payment failure (x402) if USDC balance is insufficient
