Request one for free at qrocodile.io — just enter your email address, confirm the code you receive, and your key is ready to use in the API Key node. No account, no credit card.
Yes. The nodes themselves are free, and so is the API key.
Render QR Code covers the common case: a content string and an optional built-in preset. Render QR Code With Design accepts a full design configuration — palettes, gradients, module and finder styles, logos, and the halo background decoration — for when you need complete control over how the code looks.
No. Every code is rendered from the content and design you send with the request, so changing the target later means rendering and distributing a new code. There is no hosted, editable-after-print QR code in this API.
Barcode Nodes is a general-purpose toolkit for many formats (UPC, EAN, Code 128, Data Matrix, QR, and more), and it can both encode and decode — read the content back out of an existing barcode image. QRocodile QR Code Nodes is focused entirely on QR codes and only renders them, but with the full QRocodile design system: palettes, gradients, module and finder styles, logos, and the halo background decoration. If you need styled, on-brand QR codes, use QRocodile; if you need to decode a code or work with other barcode formats, use Barcode Nodes.
