I recommend to open it in browser with logged in GCP account.

Response:

{
    'namespace': '<namespace>',
    'token': 'XXXXXXXXXXXXX'
}

QR code service

Get QR code url as url field in JSON response with lowest size

curl -X GET "https://your-app-id.appspot.com/generate?data=https%3A%2F%2Fstanwood.io&format=json&version=1

Note

• The version parameter is an integer from 1 to 40 that controls the size of the QR Code (the smallest, version 1, is a 21x21 matrix).
