# Get the Catalog summary (without lists)

`GET /catalog`

Get the catalog structure with populated number of items per list but empty lists ('lateBoundCRSes',...). It is expected that the lists are individually populated on demand via the specific methods ('CRSV2GetLateBoundCRSes',...).

## Headers
