Great! I slightly prefer api.gnome.org as it's shorter, but if tracker.api.gnome.org is easier then let's go with that.
Will Tracker maintainers be able to create and update the redirects ourselves? They will only need to change if we add/remove an entire ontology, rewire the documention, or release a new major version of tracker ... i.e. not very often, but it'd still be nice.
