Obtain a redirection link
How to obtain a redirection link for the available streaming platform, for example, watch Netflix now or watch Amazon now, etc.?

Using the TMDb API service is not possible.
The agreement made with JustWatch does not allow it.
Therefore only in the WEB interface.

@enriquemillaldeo If you would like to get deep links, you will have to talk to JustWatch yourself and get a deal done with them. Otherwise, you can point everyone to TMDB's watch pages for free.
