## 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 exchangerebel-devutils-qr-code-generator-bc22507a
```

Example prompt: Can you generate a QR code for the URL https://myshop.example.com/checkout so I can print it on my flyer?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use QR code generation without setting up a dedicated QR library or service account. Well-suited for agent workflows that occasionally need to produce QR codes as part of broader automation, especially when already using other ExchangeRebel DevUtils endpoints (e.g. FX rates).

## Known failure modes

- Missing required 'input' query parameter returns a 400 or error response
- Overly long input string may exceed QR code data capacity and fail
- Payment not fulfilled (x402) results in 402 Payment Required before content is returned
- Invalid query parameter format may result in malformed or empty response
