Re-opening until data has been reviewed and is available on the site.

Finally stumbled on this api after seeing nothing but the cookie api for extension, surprised it took so long for us to get this API, the amount of npm librairies to handle cookie is pretty crazy 😄

Hopefully the moment it gets reviewed, this API will get gain more exposure 😀
