# QR Code with Logo API
> Generate branded QR codes with a centre logo overlay, custom foreground and background colors, chosen size and error-correction level, as PNG or SVG. When a logo is supplied the error-correction level is raised automatically so the code stays scannable, and the logo is placed on a rounded white plate in the centre. Includes one-call helpers that build the correct payload for you: a Wi-Fi-join QR (SSID, password, encryption, hidden), a vCard contact QR (name, phone, email, organisation, title, URL, address) and a batch endpoint that returns up to 100 QR codes in a single request. Supply a logo by public URL, base64 or a raw binary body; receive results as base64 PNG/SVG JSON or, with raw=1, the raw image bytes. Pure server-side rendering (qrcode + sharp), no third-party upstream. Ideal for marketing and packaging, business cards and events, restaurant menus, Wi-Fi sharing and app onboarding.
