You could use Services->Snippets->Resources->ContentLoaderFunctions( e.g GetJSON) to make the REST call. This service could then be called from a Subscription which in turn would be triggered by a Timer Event(emitted by a thing implementing Timer Thing Template), to have this call made periodically.
