A ssh-keyscan -H github.com >> ~/.ssh/known_hosts suggested in the answer you mention should work, but since you are in a CMD, it should be:
ssh-keyscan -H github.com >> %USERPROFILE%/.ssh/known_hosts
Assuming:
your %PATH% includes C:\path\to\Git\usr\bin (where ssh-keyscan.exe resides)
your private key does give you access to that private repository.
Test the last point with (independently of npm), in any folder
git ls-remote git#github.com/xxxx/xxx-api.git
If you can list remote heads from that private repository, that means you do have access to it. And it should ask to add a fingerprint in %USERPROFILE%/.ssh/known_hosts if needed.
Then you can try the npm command again.
