QR code images

Any QR code as an image, from a URL: no key, no sign-up, no account. Put the URL in an <img>, a Markdown image, an email or a script, and the code is drawn at the edge and cached for good, so the same URL always gives the same image.

• /qr.png and /qr.svg choose the format; /qr is the short form (PNG, or SVG with format=svg).
• data is the only required parameter: the URL-encoded text, up to 1,500 characters. A link, Wi-Fi credentials, a contact card or plain text all work.
• size is 128 to 1024 pixels (default about 512); style is rounded or square; fg and bg are 6 hex digits; ecc is L, M, Q or H; add download=1 for an attachment.
• The names other QR image APIs use work too: text, color, bgcolor, dark, light, ecLevel, size=300x300 and colours as r-g-b, so a URL written for another service works with only the host changed.
• Images carry Access-Control-Allow-Origin: * and a year-long immutable cache. New images are braked per network; repeats come from the cache.

Showing a QR code in a chat

Chat apps that render Markdown show an image from its URL, so an assistant can answer with a code without a tool call:

![QR code for example.com](https://snip.link/qr?data=https%3A%2F%2Fexample.com)

For a code people can change after it is printed, shorten the link first (the MCP server does both in one step) and encode the short link: the destination can then change without a new image.
