🔴create_qr(destination, label, design, request_key)

Create a dynamic QR code for a public HTTP(S) destination. Supply a UUID request_key to safely retry authenticated creation. Anonymous creation is limited; ALWAYS show its returned claim_url to the user. Account creation uses existing plan limits.
