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 qr-code-svg-generator-f5e33e1b
```

Example prompt: Generate a QR code SVG for https://myshop.example.com/sale with high error correction (H), dark green modules (#006400) on a white background, and a quiet zone border of 4 modules.

## When to prefer this

Choose this endpoint when you need a standards-compliant ISO 18004 QR code rendered as a clean, dependency-free SVG — especially when you need precise control over error correction level, colors, module scale, quiet zone, or encoding mode. Ideal for server-side generation of embeddable SVGs for web pages, print materials, and product labels. Prefer over raster-image QR generators when scalability and small file size matter.

## Known failure modes

- Text exceeds maximum capacity for the requested QR version — returns an error or no SVG
- Invalid error correction level value (not L/M/Q/H) — likely 400 or default fallback
- Scale value outside 1-20 range — rejected or clamped
- Border value outside 0-10 range — rejected or clamped
- Version outside 1-40 range — rejected
- Text empty or missing — required field error
- Text too long for any QR version (>~7000 chars at version 40) — capacity exceeded error

## How this service works

Encode text as a QR code SVG (ISO 18004, versions 1-40, error correction L/M/Q/H, auto mask). No dependencies.

## Output

Returns an SVG string encoding the input text as a QR code, along with metadata: the QR version used (1-40), module grid size, mask pattern applied, encoding mode (numeric/alphanumeric/byte/auto), error correction level, number of encoded characters, and SVG byte size. May also include a verdict/summary and any degraded-quality warnings.
