# WebberSites QR Code Generator

> WebberSites QR Code Generator is a paid API for AI agents from api.webbersites.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates a scannable QR code from any text or URL, returning SVG markup, PNG as base64, and a data URI in one response.

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 webbersites-qr-code-generator-08f71358
```

Example prompt: Generate a QR code for 'https://myshop.example.com/menu' — make it 800px, use error correction level H, dark modules in #1a1a2e on a white background, and give me the SVG and PNG.

## When to prefer this

Choose this endpoint when you need a QR code returned immediately as both SVG and PNG without any server-side storage, tracking, or external network calls. Ideal for deterministic, privacy-preserving QR generation where the output must be reproducible for the same input. Supports custom colors, adjustable quiet zones, and four error-correction levels, making it suitable for branded print materials, payment URIs, WiFi sharing, and vCard encoding up to 2,000 characters.

## Known failure modes

- data parameter missing — returns 400 error
- data exceeds 2,000 characters — returns error indicating payload too large
- invalid ecc value outside L/M/Q/H — may return 400 or fall back to default
- size outside 64–2048 px range — returns validation error
- invalid hex color format for dark/light — may return 400
- margin outside 0–20 range — returns validation error

## How this service works

QR code generator: GET ?data=<text|url> and receive a scannable QR as SVG plus PNG (base64) and a data: URI. Options: size (px, default 512), margin (quiet-zone modules, default 2), ecc (L|M|Q|H, default M), dark/light hex colors. Deterministic, no network, no tracking — encode URLs, wifi, vCards, or payment URIs up to 2,000 chars.

## Output

Returns a JSON object containing: the SVG string of the QR code, PNG as a base64-encoded string, a data URI ready for embedding in HTML/CSS, the QR version number, the encoded data string, the output width in pixels, and the effective error correction level used.
