QR Codes from Google Chart API

The Google Chart API now generates QR Codes.

For example, the following URL results in the QR Code for https://brentlogan.com/.

http://chartserver.apis.google.com/chart?
cht=qr&chs=300x300&chl=https://brentlogan.com/

QR Code for http://blogan.net

Note, the above list URL is shown on two lines for space reasons only. It should be one continuous URL with no spaces.

Interestingly, the <img> form to embed the resulting QR Code in a web page does not (yet?) work. I guess that’s to be expected when using an undocumented feature of the API.

Update: The following now works:

<img src="https://chart.googleapis.com/chart?chs=100x100&cht=qr&chl=https://brentlogan.com/" />

resulting in the image below:
