upstream is a command trying to report the git repository for a given (RPM) package.
The command uses https://repology.org/project as the information source.
The heuristics used in the command is partially taken from
repology-updater/repology/parsers/parsers/gentoo.py.
upstream requires bash, xsltproc, and curl commands.
They are available as packages on Fedora: dnf install bash xsltproc curl.
