Aspose.cad offline library pricing?

I noticed the python aspose.cad library runs entirely offline & I cannot find any details about a required license.
is the library free to use?
is there a pricing page for offline use?
if there is, are there any free tools that I can use to convert files to pdf that can run offline and are free?
Thanks!

@thestart,
Hi.
You can get information about pricing here. Please generate free temporary license (you can find the reference at the top of the page) to evaluate the functionality before the purchase. Here is the helpful information about license types.
