## 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 x402tools-qr-generator-f0c711fb -d '<json body>'
```

Example prompt: Can you generate a 512px PNG QR code for the URL https://myshop.example.com so I can put it on my flyer?

## When to prefer this

Choose this endpoint when you need a quick, pay-as-you-go QR code generation call without a subscription, especially when building agents that require micropayment-compatible APIs or when you need flexible output formats (PNG, SVG, base64) and configurable image sizes.

## Known failure modes

- Missing or empty `text` field returns an error indicating required input
- Invalid `format` value outside the enum returns a validation error
- Unpaid or failed x402 payment results in a 402 Payment Required response
- Extremely large `size` values may be rejected or time out
- Non-printable or binary content in `text` may produce unreadable QR codes

## How this service works

Generate a QR code from any text, URL, or data. Returns a scannable PNG, SVG, or Base64 image. Use for QR code creation, link encoding, and barcode generation.

## Output

A JSON object containing a `dataUrl` field with the QR code encoded as a base64 data URI (e.g. `data:image/png;base64,...`), ready to embed in HTML or decode as an image file.
