How can I programmatically get server warranty information?

I'm trying to write a python script to retrieve current warranty information for our Dell poweredge servers using the service tag as a parameter.

Web searches turned up this request

https://api.dell.com/support/assetinfo/v4/getassetwarranty/(service tag)?apikey=(api key)

But I get a "404 not found" error when using it.  Has this endpoint been retired? 

If so, what alternatives are there? I'm in an all-Linux shop so I cannot use any Windows utilities.
