So you need the remote repository URL. Maybe because you are trying to git add remote. You can type the below text to get the full info (needs to be done inside the folder you are working in):
git remote show origin
OR
git config --get remote.origin.url
After you know this, if you want you can create a new remote branch
git add remote <name you want for your new branch> <URL you just got>
git add remote newbranch git@hostedgit.yourdomain.com:name/project.git
