A DocBlock is required in app/code/Test/Calculator/Api/CalculatorInterface.php as described here: http://devdocs.magento.com/guides/v2.0/coding-standards/docblock-standard-general.html

<?php

namespace Test\Calculator\Api;

interface CalculatorInterface
{
    /**
     * Add two numbers.
     *
     * @param int $num1
     * @param int $num2
     * @return int
     */
    public function add($num1, $num2);
}

To process the payment you can use the native API of the payment method, but you can use these methods to get the payment methods available and to place an order in Magento using the REST API.

Get Payment Method

curl -g -X GET "XXXXX_STOREURL_XXXXX/index.php/rest/V1/guest-carts/56241bf6bc084cd7589426c8754fc9c5/payment-information" \
    -H "Authorization: Bearer XXXXX_TOKEN_XXXXX" 

Place Order

curl -g -X PUT "XXXXX_STOREURL_XXXXX/index.php/rest/V1/guest-carts/56241bf6bc084cd7589426c8754fc9c5/order" \
    -H "Authorization: Bearer XXXXX_TOKEN_XXXXX" \
    -H "Content-Type:application/json" \
     -d '
{
    "method": {
        "method": "checkmo"
    }
}
