This endpoint is mostly used for TorneAUTH, but can partially (when development has finished) also be used as a dynamic DNS API. And for the sake of code, it has to be documented.
Data is transferred with either GET or POST for the moment which is a bit different to for example the DNSBL API, which also honors PUT and DELETE.
Full access to this interface can normally not be requested, except for the special access to the dynamic DNS system.
