I wonder if it is possible to fetch data from a remote api while user is typing a new post inside the editor. That data should be shown anywhere in the screen (I mean, inside the editor). Is that possible? If so, how? Thank you very much in advance

Data to be fetch: video title 1, link to video title 1, code to embed video1 into post. video title2, link to video title2, code to embed video 2 into post.

This development will be installed on many machines. I think it should be a plugin. I am thinking about making a Chrome extension as well

Please take into account that data should be fetched while user is typing a new post and that data should be shown on a sidebar (while user is typing). The idea is that the user types some characters, data is fetched based on those characters. Data received is code to embed a video inside post
