My suggestion would be to do as for (guix ci): make a (guix data-service-client) (?) module that contains proper bindings to a subset of the Data Service APIs, using =E2=80=98define-json-mapping=E2=80=99. Once we have that, we can consider using it in =E2=80=98guix weather=E2=80= =99 or in new tools such as the proposed =E2=80=98guix git log=E2=80=99. Ludo=E2=80=99.
