It’s pretty simple.

You subscribe to get access to the API, you and you just insert the id of the series or movie on the query id parameter.
If you don’t know how to find the id, you just have to go on the Netflix website, find the page of the series/movie you want, and you will find the id in the link of the page.

This API will return a proper json that you can exploit in your website or how are you pleased.
Remember that you want the the information not regularly, but just to know details about a series and where to find it so you can easily connect to VPN, just use our website
www.findmyseries.net . The netflix catalog ( and more platforms to come ) is updated once every month.
