Create and SAVE a QR code in the customer's qr-cow account (it appears on their dashboard and is tracked). Pick a content type and pass the content as a string. Static codes are unlimited on every plan; dynamic codes (editable + scan analytics) have a per-plan limit (the free plan includes a few). To just render a styled image without saving, use render_styled_qrcode instead.

Render a fully STYLED QR code image (colours, dot + eye shapes, gradient, logo, error-correction) from data and a style, WITHOUT saving it to the account. Great for generating codes in bulk. Use a preset for a ready-made look and/or set style fields to override. Returns the QR as an image (png/jpg) or SVG source. Stateless: this calls POST /v1/qr/render and stores nothing.

List the customer's recent QR codes, newest first.

Fetch full details for one QR code by id, including current redirect URL for dynamic codes.

Update a dynamic QR code's destination URL. The printed code doesn't change — only what scanning it leads to.

Soft-delete a QR code. Scans afterwards return 404.

Fetch scan analytics for one QR code: total scans, unique scanners, breakdown by country, device, and hour of day.

Return the authenticated user's profile + plan info.
