Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agishub-qr-code-generator-a6e78c7a -d '<json body>'
```

Example prompt: Can you generate a QR code for https://myshop.com/sale — use high error correction (H level), a module size of 8, and a margin of 4 cells?

## When to prefer this

Choose this endpoint when you need a fast, server-side QR code generated as an SVG (scalable, resolution-independent) plus a data URI — especially when you need fine control over error-correction level, module pixel size, and quiet-zone margin. Prefer this over client-side libraries when generating QR codes in a headless or agent workflow without browser access.

## Known failure modes

- Missing 'text' query parameter returns a 400 error
- Module size or margin values outside allowed ranges (size 1-40, margin 0-20) return a validation error
- Empty string for 'text' fails minLength validation
- Invalid ec_level value not in [L, M, Q, H] returns a validation error

## How this service works

Generate a QR code for any text or URL. Returns an inline SVG plus a data URI, with selectable size, quiet-zone margin and error-correction level.

## Output

Returns a JSON object containing an inline SVG string of the QR code and a data URI (base64-encoded image), ready to embed in HTML or download, encoded with the specified text, module size, margin, and error-correction level.
