## 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 qr-code-generator-52646986 -d '<json body>'
```

Example prompt: Can you generate a URL-type QR code for https://myshop.example.com at 400 pixels so I can drop it into my product flyer?

## When to prefer this

Choose this endpoint when you need a quick, paid-per-call QR code generated from a URL, text, vCard, or Wi-Fi string and want a raw PNG back — especially in automated agent workflows where you need to embed a QR image in a document, flyer, or web page without setting up your own QR library.

## Known failure modes

- Missing required 'data' field returns a validation error
- Unsupported 'product' enum value causes a 400 error
- Extremely long data strings may exceed QR code capacity and fail encoding
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Invalid size value (e.g. non-integer) may return a 400 error

## How this service works

QR code generation on demand (x402, USDC on Base).

## Output

Returns a JSON object with a 'status' field indicating success and a 'qr_code_png' field containing the QR code image as a base64-encoded PNG string, along with the image size in pixels.
