Which CDN service can store paid video content?

Question

Payment systems

Good afternoon,
There is a site with personal accounts of users who buy video content.
We want to organize a system with the issuance of one-time keys for viewing it, preferably on the site itself through the service API. And preferably without the ability to download vidos.
Further, it is planned to catch a callback upon completion of the view to perform certain actions.
Please tell me if there is something similar on the net? So that it was impossible to look directly, but only by token / key on the service or through Api on the site itself.

Answer 1

Initially CDN is not for this.
Cloud Storage is suitable for your task, for example, Selectel (they have Storage based on OpenStack Swift, that is, see the documentation on OpenStack). The CDN is built in.
As alternatives - S3 (not necessarily from Amazon, many offices provide a compatible API)
In the API of various Cloud Storage - there are all these "temporary access tokens".
PS:
And if you don't want to saw with your own hands, then you can use either video hosting or video streaming services or video streaming software. In developed projects, all this temporary access is provided.
For example, erlyvideo.ru
