Embeddable HTTP API

The basic generator is also exposed over HTTP: handy for embedding a QR code directly in an email, a page or a script, with no JavaScript. Open CORS, no key, cached response.

Note: the API returns a "simple" QR (solid colors, square modules). Advanced styles — shapes, gradients, logo, frame — are available only in the generator above, in the browser.
