is there a command or a way to find how good or bad is the Geoclue Demo Agent?

In startup applications in Debian (as possibly other debian and ubuntu based distros.) there is a library called Geoclue Demo agent, the actual library with path is /usr/libexec/geoclue-2.0/demos/agent which is part of geoclue-2.0 https://gitlab.freedesktop.org/geoclue/geoclue/wikis/home . The only question I know which has been asked so far is to remove the app/service. See the question from unix.stackexchange.com . I would find it more interesting if I could understand what it shows and how it shows it. The manpage written about man geoclue isn't addressed for ordinary users. Can somebody help me with that ? I am looking on lines something simple as curl wttr.in/$location and you get output of weather of that location. Something which is interactive and it probably is, just need to figure out how.
