Browser Extensions + Bubble

Hi Bubblers!
I’m building a browser extension that retrieves the data of the current video watched in the browser using the YouTube API and in the future the user’s Gmail/YouTube account. After the extension pulls that data I want to populate the fields of data type that I have going on Bubble. Now the question is: Since an API requires an endpoint URL, how do I get an endpoint for my browser extension? Since extensions don’t have URLs, nor a proper database, how do I transfer those values (video information + user logged in the browser) to my Bubble database?

I hope I made clear what the functionality is supposed to be.

Thanks in advance for your help!
