What it can do

  • Generate Qr Code: Use this when the user wants a new QR code that is also a picture: a scannable code painted into art from a description, that opens a link. It starts the code and answers at once wit
  • Get Qr Code: Use this when you have a QR code’s id (from generate_qr_code or list_qr_codes) and need its status or finished image. While the code is still being painted it waits up to `wait` seconds (
  • List Qr Codes: Use this when the user asks about QR codes they already have, newest first, a page at a time (pass nextCursor as cursor for the next page). Do not use it to make a code.

What data it sees

Do you need an account

No: the server works without sign-in

QRX turns a text prompt and a link into a branded QR code that is also a piece of art: a lighthouse at dusk, a watercolour bouquet, a pixel-art city, in your brand colours. Each code is decode-checked before it is delivered and points at a hosted qrx.to short link that can be re-pointed later, so it is ready for posters, menus, packaging, signage and slides.

Raw names from tools/list. Only developers need these.

generate_qr_codeUse this when the user wants a new QR code that is also a picture: a scannable code painted into art from a description, that opens a link. It starts the code and answers at once with its id while the picture is painted, which usually takes under a minute; then call get_qr_code with the id to wait for the image. Do not use it to look at, list or change codes that already exist. Each code counts against the user’s QRX allowance.
get_qr_codeUse this when you have a QR code’s id (from generate_qr_code or list_qr_codes) and need its status or finished image. While the code is still being painted it waits up to `wait` seconds (25 by default) for it to finish before answering, so call it again if it is still processing. Do not use it to make a new code.
list_qr_codesUse this when the user asks about QR codes they already have, newest first, a page at a time (pass nextCursor as cursor for the next page). Do not use it to make a code.
change_qr_code_destinationUse this when the user wants an existing link QR code to open a different web address. Printed copies follow at once. It only works for link codes, and only if the account’s plan allows changing destinations. Do not use it to make a new code.
get_accountUse this when the user asks how many QR codes they can still make today, when the daily count resets, or what their QRX account can do. Do not use it to make or list codes.
get_profileUse this when you need to know which QRX account is connected, for example to confirm it with the user. Do not use it for limits; use get_account.
list_stylesUse this when the user wants to choose a look for a new QR code; pass a style id to generate_qr_code. Do not use it to make a code.
