All browse endpoints are paginated, returning 15 records by default. You can use the page and limit parameters to move through the pages of records. The response object contains a meta.pagination key with information on the current location within the records: 
"meta":{
    "pagination":{
      "page":1,
      "limit":2,
      "pages":1,
      "total":1,
      "next":null,
      "prev":null
    }
  }
