I want to make a website where users can login through Snapchat. Can Snapchat provide the API for my website where the user can see other people's profile on website and user can add them on Snapchat?
There are some APIs available for for developers to use. They're hosted on the GitHub and they're free. For each of the libraries you have to use various files like NodeJS or a KIT.

I've also tried to get the details for the official API, but there aren't any.
