What you should know

Tools exposed: generate a QR code, build typed payloads (WiFi, vCard, UPI and more), decode an image, and verify that a styled code still scans.
Nothing is stored server-side and no account is created.
Because the API is keyless, Claude can also embed a QR image inline in an artifact or a markdown answer without any setup at all.
