Is this package legal?

[AnalyzePlatypus]

This package uses Fast.com's private API.
(Fast.com is a public site by Netflix. It runs on their infrastructure)

I have not been able to find any evidence that they allow their API to be used by third parties.

Is using this package legal?

Nope, it's not legal. It even asks to use the token which fast.com uses.
