Wget a file from github

I would like to wget this file:

https://github.com/cms-jet/JECDatabase/blob/7fbf741eaa2159b609e194e47046d4cc4d7cec86/tarballs/Summer16_23Sep2016V4_MC.tar.gz

I try as usually:

wget https://api.github.com/repos/cms-jet/JECDatabase/contents/tarballs/Summer16_23Sep2016V4_MC.tar.gz --header="Accept: application/vnd.github.v3.raw"

However, there is a problem:

--2021-11-18 18:01:18-- https://api.github.com/repos/cms-jet/JECDatabase/contents/tarballs/Summer16_23Sep2016V4_MC.tar.gz?raw=true
Resolving api.github.com (api.github.com)... 140.82.121.5

HTTP request sent, awaiting response... 403 Forbidden
2021-11-18 18:01:19 ERROR 403: Forbidden

Why does the above command fail? Is it because it is a tar.gz (raw) file?
