QR code
QRtag.net's free API generates a QR code image on the fly from a plain URL you can drop straight into an <img> tag: https://qrtag.net/api/qr_[size].[png|svg]?url=[URL]. If no url parameter is supplied it falls back to the page's HTTP referrer, which makes it handy for site-wide "scan to share this page" widgets. It's capped at 1,000 requests per 10 minutes per application and caches generated codes for 3 days.
