How to Get URL addresses of Raw Files from a Gist Address

I am wondering how to get the URL addresses of raw files from a gist address.

In the above address, by calling the Github API address,
I was able to get the addresses of the raw files through the response of JSON.

However, I couldn’t get the address of the raw files at the following address.

I wonder if there is a way to get the address of the raw files from the above address through the Github API.
