## 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 x402-gateway-qr-code-generator-da45bd98 -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.example.com/promo — I want to put it on a flyer?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call QR code generation capability without API keys or subscriptions, especially in agent workflows where micropayment (x402/USDC on Base) is already supported. Ideal for one-off or low-volume QR code generation tasks embedded in automated pipelines.

## Known failure modes

- Invalid or missing tool parameter returns an error
- Unsupported input format or encoding type may result in a generation error
- Payment failure or insufficient USDC balance causes a 402 rejection before generation
- Malformed URL input may produce an unreadable QR code
- Network timeout if the upstream generation service is unavailable
