QR code

The QRtag.net API generates QR code images that can be embedded directly via a URL, returning PNG (opaque or transparent) or SVG files with optional pixel‑size and custom target‑URL parameters. The images are cached for three days and the free service is limited to 1,000 requests per 10 minutes per application.
