I love your project and would like to help, but I don't like the idea of all my private data (like email address and work before together with my telegram name) in this public thread and a public speadsheet. What is the reason to publish all this data? Perfect for phishing and spoofing.

I would like to get one!

EDIT: Bought it, works perfect, thx!

I think it would be a good idea if someone is proofreading this.
And then, your method is really boring. Just another (in many countries) illegal pyramid scheme with altcoins.
But, maybe someone is interested and it's for free.

And, if you really want people going to sign up, don't put links with "click here" in a ebook. Put the URL in (maybe with shortener).

I don't think it's just an normal (502) error. The 503 shows the request is bad. And it's just with a few courses but they have always this error.
In a long list it doesn't work and in a short list, not too. But every other course in the list works fine, it's always the problem with the same courses.

But didn't change anything on the broken courses, I just now got the HTTP-Error:


But if I create a account myself and click on trial, everything works fine.
I don't know why the API should any be broken on this course?
Maybe there is an error in parsing the course id?

It's okay, but there are many popular courses which are broken. 
But it is still the best tool to download on udemy I know.
Just search on the internet to get it a bit cheaper
