Get all options for configurable product Magento 2.0 REST Api

When i call this API,

{{base_url}}index.php/rest/V1/configurable-products/:sku/options/all

I am getting a response like this,

[
  {
    "id": 9,
    "attribute_id": "93",
    "label": "Color",
    "position": 0,
    "values": [
      {
        "value_index": 15
      },
      {
        "value_index": 16
      },
      {
        "value_index": 17
      }
    ],
    "product_id": 19
  },
  {
    "id": 10,
    "attribute_id": "176",
    "label": "side",
    "position": 1,
    "values": [
      {
        "value_index": 18
      },
      {
        "value_index": 19
      }
    ],
    "product_id": 19
  }
]

But i want label for all these value_indexes.Could i get all these values in a single request

There is an pi for getting all the labels,

{{base_url}}/index.php/rest/V1/products/attributes/:attribute_id/options

Ex:

{{base_url}}/index.php/rest/V1/products/attributes/93/options

will return

[
  {
    "label": " ",
    "value": ""
  },
  {
    "label": "green",
    "value": "12"
  },
  {
    "label": "yellow",
    "value": "13"
  },
  {
    "label": "red",
    "value": "14"
  }
]
