Everything the QR code generator
does, as one GET request. No account, no API key — the URL is the
image, so you can drop it straight into an <img> tag, a README, or an
email signature.
GET https://in.bio/api/qr?url=https://example.com<img src="https://in.bio/api/qr?url=https://example.com&dot_style=dots&marker_shape=circle&foreground=1a56db" alt="QR code" width="256" />Responses are the raw image (image/png by default, image/svg+xml with
format=svg), cached for a day. Rate limit: 30 requests/minute per IP.

Want click tracking?
A QR code from this endpoint encodes your URL directly, so scans go straight to the destination — untracked. To count scans, shorten the link first (also free and keyless) and generate the QR code for the short URL, or create the link from a free account where every link’s QR code and scan analytics live together.
