## 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 gadgethumans-qr-code-generator-62563621
```

Example prompt: Generate a QR code for 'https://myshop.com', make it 300x300, use dark blue foreground with white background, high error correction, and return it as a PNG.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) QR code with color and format customization options and no API key is required. Ideal for agents needing on-demand QR generation with configurable error correction levels and custom branding colors without setting up a dedicated QR service.

## Known failure modes

- Empty or missing text parameter returns an error
- Invalid color values (non-hex, unsupported formats) may cause generation failure
- Unsupported output format string returns an error
- Excessively long text strings may exceed QR code data capacity
- Invalid ECC level string may return a parameter error
- HTTP 402 if payment is not provided
