"description": "Render a QR code for any of six content types: a link, plain text, a v-card contact, a pre-filled email, a phone number, or a pre-filled SMS. The image is returned as a PNG you can look at. Nothing is stored, so this code is STATIC: it encodes the content directly and cannot be changed after it is printed. If the user wants a code they can repoint later, or wants to count scans, create a short link with create_short_link first and then call get_link_qr_code instead. Link and Text work on every plan; V-card, E-mail, Call and SMS require Flyn Pro, as do custom colours and SVG output. WiFi codes contain the network password, so they are made in the Flyn dashboard's QR builder, not through this tool: never ask the user for a WiFi password.",
