Generating a QR code using the NXT / Ardor api for scanning

Question

Currently the nxt gui generates a QR code for certain pages where you can scan with your phone or another computer to do an air gap transaction. How can you do this via the api?

Answer 1

https://nxtwiki.org/wiki/The_Nxt_API_Examples#Encode_QR_Code

You can do the following:

http://localhost:7876/nxt?
  requestType=encodeQRCode&
  qrCodeData=NXT-7A48-47JL-T7LD-D5FS3&
  width=100&
  height=100

Or via the command line:

curl -d requestType=encodeQRCode -d qrCodeData=NXT-XXX-XXX-XXX-XXX -d width=100 -d height=100 http://localhost:7876/nxt

You can use it in an image tag like this:

< img src="data:image/gif;base64,R0lGODlhEAAQAMQAAO....." width="100" height="100" />
