URL shortening link for QR code generation

Hi,

I like to add a sticker to the back my top loader sleeves so that I can easily scan a QR code and it automatically pulls up current market data on my physical cards which cuts down time immensely when I'm at a card show or selling via other means. I do this via an export from the current app I'm using for pricing which is shiny that gives me a price charting ID. I then add the shortened url and query the id column to automatically produce a QR code when I print all my labels Directly from excel or Google sheets.  price charting I don't easily have the option of a shortened url without api access and having my own token. I know a lot of people who do this with their collections. If there was an easy way or easy way to find documentation or just a link to a shortened url without needing additional data and possibly even including the code for an excel spreadsheet or a link directly to a QR code that can be generated for collectors who like to do this specifically so they can download the image on the product page. Could make it premium feature even. But I'd bet just a button on a page to generate a QR code or to provide a shortened url where the item id could be input in would be appreciated.
