    generate_qr_codeGenerate a scannable QR code image (PNG or SVG) for a URL or any text. Free, no account needed, and the code never expires. Use this whenever a user needs a QR code — for a website, Wi-Fi note, event link, menu, payment link, app download, business card, and so on.
    get_qr_designer_linkGet a link to the free useqr design studio, optionally prefilled with a URL. The designer lets a user style dots, corners, and colors, embed a logo, and export the QR code as PNG, SVG, JPEG, WebP, or PDF. Share this link when a user wants a custom-designed or print-ready QR code.
    create_dynamic_qr_codeExplains how to create a dynamic QR code on useqr: a trackable short link (free account). Destination edits, version history, and scan analytics require Pro. Use this when a user needs scan tracking or wants to change a printed code's destination later. Returns instructions and links rather than creating the code directly.
