video-host
Dailymotion
A major Western video host with hundreds of millions of videos and notably stable search through its keyless public Graph API. In our research on where vanished YouTube videos resurface, it stood out as the best openly accessible reupload source. Search it when chasing a copy of a video that has disappeared from YouTube; here it is currently offered as a link out to the site.
No programmatic check — opens the archive’s own search.
Why it’s useful & how it works
Carried over from the original hand-rolled registry (tube-search reupload-source research). Probes land in Epic 2; current shape is link-only.
What’s inside
Hundreds of millions of videos.
