#[05AB1E](https://github.com/Adriandmen/05AB1E), 22 bytes

Assumes that the **URL** is passed *without* the `https://`. 

###Code:

    .w’®Ã-ƒ¢’¡`"<li>"¡2è#¬

Uses the **05AB1E** encoding. Cannot be tried online, because of internet access.

###Explanation:

    .w                       # Receive implicit input and read all data from the url
      ’®Ã-ƒ¢’¡               # Split on the string "header-details"
              `              # Flatten once which leaves the last element on top of the stack
               "<li>"¡       # Split on the string "<li>"
                      2è     # Get the third element
                        #    # Split on spaces
                         ¬   # Retrieve the first element 


This is what I get when running in the command line:
