Instead of relying on GitLab's API, it's probably a better idea to just use git remotes properly. I put together a script [0] to automate the process to set the primary remote to Sourcehut (git.sr.ht) and mirror to GitLab and GitHub. And yes, that script is in a repo that's also mirrored to GitHub and GitLab (check the README). It combines well with my `git pushall` alias [1].
