Search engine for YouTube content that's no longer on YouTube:
deleted, removed, region-blocked, DMCA'd. ~1.5B videos indexed from 2005
onwards by aggregating archive sources Internet Archive Wayback Machine
(CDX + HEAD-spread discovery), Common Crawl.
What you get for any video ID: metadata (title, description, channel,
upload date, duration, view counts, tags), thumbnails, original captions
when the archive captured them, and reconstructed URLs to play the
archived video file when available. Channel discovery reconciles legacy
username/handle eras to a single canonical identity (lots of channels
renamed themselves a dozen times — that part was painful).
