## 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 fittings-qr-code-generator-50e161d9 -d '<json body>'
```

Example prompt: Generate a QR code for https://mystore.com as a PNG, with H error correction, scale 10, a 3-module quiet zone, dark modules in #1a1a2e and a white background.

## When to prefer this

Choose this endpoint when you need a fast, highly configurable QR code rendered as SVG or PNG — especially when custom branding colors, precise module scale, or specific error-correction levels matter. It is ideal for agents that need to embed QR codes in documents, marketing assets, or event materials without relying on a client-side library.

## Known failure modes

- Content exceeds 271 UTF-8 bytes — returns an error indicating the payload is too large
- Invalid hex color format — may return a validation error
- Scale or border value out of allowed range (scale 1–16, border 0–8) — returns a validation error
- Invalid format value (not 'svg' or 'png') — returns a validation error
- Invalid errorCorrection value (not L/M/Q/H) — returns a validation error
- Empty content field — returns a validation error

## How this service works

Generates a QR code for arbitrary text or a URL as SVG or PNG, with a chosen error-correction level, module scale, quiet zone and colors.

## Output

Returns a QR code image file — either an SVG vector or a PNG raster — encoding the provided text or URL. The image reflects the chosen error-correction level (L/M/Q/H), pixels-per-module scale (1–16), quiet-zone border width (0–8 modules), and custom dark/light hex colors.
