GeoServer's REST API is used for administrative tasks and as such does not provide a way to see the actual data you have stored in the database, just the details of how GeoServer is connecting to the database and some metadata about the store.
To access the actual data you need to use the WFS endpoint which is described by the OGC WES Specification and described in the GeoServer manual.
If you must have REST access to the features you could use the experimental OGC Features API module to do this.
