Closed-source, very-limited-API platforms like Tik Tok do not actually let you "play with the thing". What I imagine you would be interested in is a client which, say, gets the text version of a large number of short videos, filters those texts based on criteria you have defined and meta-data from TikTok (time, number of views, some proxies for a 'quality' measure) and serves you up with the results in a textual form, or perhaps a page with titles/summaries and links to the text and the video.

I'm not sure that's worth it but I'm willing to be this is not possible to achieve.
