Magento 2 REST API – Returns Only Default Category and Children

categorycategory-treemagento-2.1magento2rest

I am using "rest/V1/categories/" (Magento 2 Rest API). In documentation(devdocs.magento.com/swagger/#) it says "Retrieve list of categories" but it only returns default category(and its all children) every time. How can i get the list of all categories(those which are parent including default)
enter image description here

This is how i am doing it,

public function getCatagory($data){
        $response = array();
        if(isset($data['categoryId'])){
            $url = $this->baseUrl."rest/V1/categories/".$data['categoryId'];
            $response = $this->curlGet($url,$this->token);
        }else{
            $url = $this->baseUrl."rest/V1/categories/";
            $response = $this->curlGet($url,$this->token);
        }
        return $response;
    }

I am executing else part here "rest/V1/categories/" and i am getting,

{
  "id": 2,
  "parent_id": 1,
  "name": "Default Category",
  "is_active": true,
  "position": 1,
  "level": 1,
  "product_count": 0,
  "children_data": [

  ]
}

It only giving me default why are the other categories missing as shown in the attached image of admin panel. Please help!! Thanks i advance(I don't want to put all my categories under default as children, i know its a way out, but i have already made each of them a parent as they are shown in the images attached now i just want to fetch them).
