https://tikwm.com/originalDownloader.html is basically the only public service that gives source quality
awemer used for scraping uses that and there's no scrape limits bar it breaking sometimes or being slow, no captcha.
an attach option would take a tiktok url as input, look up the video via tikwm (likely that page) then attach the resulting file as an upload file. presumably copying it from tikwm to endchan server and attaching that directly instead of like downloading it then reuploading it as a blob or whatever with the existing file upload functionality would make more sense. idk how endchan is coded or what would be feasible.

unsure if this helps
