API Documentation

Create several Static QR Codes easily and add them to your Application.

Get started with our Live QR Code API

To get a QR code graphic as a PNG image, send our system a GET request using the following:
https://www.api.live-qr.com/_functions/format/width/foreground_color/background_color/data

Request the following URL to test it out straight in your browser:
https://www.api.live-qr.com/_functions/png/200/000000/ffffff/RXhhbXBsZQ==

As you can see, it's easy to embed a QR code in your (X)HTML documents by using the <img> tag. 
<img src="https://www.api.live-qr.com/_functions/png/200/000000/ffffff/RXhhbXBsZQ=="/>
produces/shows the following QR code image:

Additional notes: We do retain the power to reject API requests. This is particularly true for requests that we deem to be impolite or abusive (i.e., if it seems to be a DoS assault). Since the contents of the QR codes are not recorded, we only keep track of the source of all queries (referrer and IP address; for more details, see the guidelines on our privacy policy). If your service consistently generates more than 10,000 requests per day, do inform us.

Parameters:

You may use the Live QR Code parameters listed below to create your own QR Codes now that you have a rough understanding of what our API is capable of. Both HTTP-GET and HTTP-POST are valid submission methods for all parameters. You may also combine the two approaches. When a parameter is supplied simultaneously with a POST and GET request, the GET value is utilized and the POST value is disregarded.

Note: The text submitted via the "data parameter" is not encoded. You have to encode it to Base64 format.
