Looks like YouTube disabled its get_video_info endpoint. I'm not sure if the bypass still works.
Changing your date birth isn't enough anymore. In order to watch age-restricted videos you have to verify yourself using personal documents. Not with this script though.
Bypass video age restrictions by abusing the fact that calling https://www.youtube.com/get_video_info does not require any verification. The script intersects default JSON.parse method which YouTube uses to decode AJAX responses. The bypass might be only temponary, since YT can enforce authentization for every single AJAX call.
In that case youtube-dl will be the only available option.
- Watch age-restricted videos without having to verify your age.
- Watch age-restricted videos without even being logged in (unstable?).
- Watch restriced videos in embeds (without having to open YouTube).
- ADBlock support - watch age-restricted videos while still seeing no ads.
Install this script with Tampermonkey (or Violentmonkey etc.) extension avalaible for all modern browsers.
Tampermonkey (and similar extensions) should automatically recognize install links:

Otherwise install the script manually.
