How to download an individual file

I would like to download the file:

https://github.com/pfs/TopLJets2015/blob/967244cdecb01bfc0b9cd62e9808a73a72b2a2c2/TopAnalysis/interface/CommonTools.h

I try

wget https://api.github.com/repos/pfs/TopLJets2015/contents/bin/TopAnalysis/interface/CommonTools.h --header="Accept: application/vnd.github.v3.raw"

and I get an error:
