Expected result (*)

1. Price is present in both last two responses and is not equal to zero or is equal to real price whatever price was specified in the request payload.
2. No side-effects on Storefront

Actual result (*)

1. Fresh cart always has no price property. Submit an order and you will be able to reproduce again.
2. Zero price in the Cart on Storefront
   

Information from reporter

I have created a Product with a prize of $24 using the backend of Magento2. When I check it in the backent it is fine.
However, when I add one unit of it to an existent cart using the REST API I get a price of zero. For that I call [POST] /carts/mine/items with body:

{
    "cart_item": {
        "quote_id": "2",
        "sku": "MY_SKU",
        "qty": 1
    }
}

I get the following response:

{
  "item_id": 2,
  "sku": "MY_SKU",
  "qty": 2,
  "name": "My Product",
  "price": 0,
  "product_type": "virtual",
  "quote_id": "2"
}

Also when I call [GET] /products I get the right price in the response, this is the response I get:

{
  "items": [
    {
      "id": 1,
      "sku": "MY_SKU",
      "name": "My Product",
      "attribute_set_id": 9,
      "price": 24,
      "status": 1,
      "visibility": 4,

      "created_at": "2016-01-11 19:17:10",
      "updated_at": "2016-01-13 17:49:11",
      "product_links": [],
      "options": [],
      "tier_prices": [],
      "custom_attributes": [
        {
          "attribute_code": "meta_title",
          "value": "My Product"
        },
        {
          "attribute_code": "meta_keyword",
          "value": "My Product"
        },
        {
          "attribute_code": "meta_description",
          "value": "My Product"
        },
        {
          "attribute_code": "options_container",
          "value": "container2"
        },
        {
          "attribute_code": "required_options",
          "value": "0"
        },
        {
          "attribute_code": "has_options",
          "value": "0"
        },
        {
          "attribute_code": "url_key",
          "value": "my-product"
        },
        {
          "attribute_code": "tax_class_id",
          "value": "0"
        },
        {
          "attribute_code": "custom_time",
          "value": "2016-01-11 00:00:00"
        }
      ]
    }
  ],
  "search_criteria": {
    "filter_groups": [
      {
        "filters": [
          {
            "field": "custom_time",
            "value": "2015-11-19",
            "condition_type": "gt"
          }
        ]
      }
    ]
  },
  "total_count": 1
}

Any guesses why this might be?

[degaray]

The problem comes here: Magento\Quote\Model\Quote\TotalsCollector::collect because all totals are set to zero and then all totals are calculated per address set. Since no address is set, then no totals are calculated, and as result, it does not calculate any total.

[ishakhsuvarov]

@degaray Could you please provide more detailed steps to reproduce the issue? How did you create your quote and customer?
A set of empty addresses should be created together with the quote, allowing normal totals calculation for this case.

[degaray]

1.- I create a new instance of Magento2 using git clone --recursive https://github.com/rgranadino/mage2_vagrant.git to get a fresh install. Then I follow all the steps to install it using composer, etc.
2.- I oath login as admin using /integration/admin/token:

    {
        "username": "admin",
        "password": "password123"
    }

I get an auth token.

3.- I create a product calling: [POST] /products:

    {
      "product": {
        "sku": "MY_SKU",
        "name": "My Product",
        "attributeSetId": "4",
        "price": 20,
        "status": 1,
        "visibility": 4,
        "typeId": "virtual",
        "weight": 0,
        "extensionAttributes": {
          "stockItem": {
            "stockId": 1,
            "qty": 20,
            "isInStock": true,
            "isQtyDecimal": false,
            "useConfigMinQty": true,
            "minQty": 0,
            "useConfigMinSaleQty": 0,
            "minSaleQty": 0,
            "useConfigMaxSaleQty": true,
            "maxSaleQty": 0,
            "useConfigBackorders": false,
            "backorders": 0,
            "useConfigNotifyStockQty": true,
            "notifyStockQty": 20,
            "useConfigQtyIncrements": false,
            "qtyIncrements": 0,
            "useConfigEnableQtyInc": false,
            "enableQtyIncrements": false,
            "useConfigManageStock": true,
            "manageStock": true,
            "lowStockDate": "string",
            "isDecimalDivided": true,
            "stockStatusChangedAuto": 0,
            "extensionAttributes": {}
          }
        },
        "options": [],
        "tierPrices": [],
        "customAttributes": [
        ]
      },
      "saveOptions": true
    }

4.- I create a user using [POST] /customers:

    {
        "customer": {
            "email": "my@email.com",
            "firstname": "My Name",
            "lastname": "Last Name",
            "storeId": 1,
            "websiteId": 1,
            "extension_attributes": {
            },
            "addresses": [
                {
                    "country_id": "MX",
                    "street": [
                        "Some address 23"
                    ],
                    "telephone": "5555555558",
                    "postcode": "10200",
                    "city": "México",
                    "firstname": "My Name",
                    "lastname": "Last Name",
                    "default_shipping": true,
                    "default_billing": true
                }
            ]
        },
        "password": "{{customer_password}}"
    }

4.1- I login using /integration/customer/token and get an oath token.

5.- I create a cart using: [POST] /carts/mine with a blank body

6.- I add an item to the cart using: [POST] /carts/mine/items

    {
        "cart_item": {
            "quote_id": "1",
            "sku": "MY_SKU",
            "qty": 1
        }
    }

7.- I finally call [GET] /carts/mine/payment-information
and I get this:

    {
      "payment_methods": [
        {
          "code": "checkmo",
          "title": "Check / Money order"

      ],

        "items_qty": 1,
        "items": [
          {

            "price": 0,

            "weee_tax_applied": null,
            "name": "My Product"
          }
        ],
        "total_segments": [
          {
            "code": "subtotal",
            "title": "Subtotal",

          },
          {

            "title": "Shipping & Handling",

          }
        ]
      }
    }
