## 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 omniapi-qr-code-generator-516e8dd3 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call QR code generation without setting up a dedicated QR library or service account. It is well-suited for agents that need to generate QR codes on demand for arbitrary URLs or text strings and can pay via USDC x402 micropayments. Prefer alternatives if you need bulk batch generation, custom styling (colors, logos embedded in QR), or if you need guaranteed SLAs.

## Known failure modes

- Empty or missing query/input field returns an error
- Input string exceeds maximum encodable length for QR codes
- Payment failure via x402 micropayment protocol blocks the request
- Malformed input schema (missing required 'query' field) returns 400
- Service unavailability on the Vercel-hosted backend returns 5xx
