# NAS overview

Available in VPC

## Overview

NAVER Cloud Platform is a cloud service built with NAVER's latest computing technology and operational know-how. The application program interface (API) that supports the use of services and solutions provided by NAVER Cloud Platform is called NAVER Cloud Platform API. NAVER Cloud Platform API is provided in the RESTful format, and is run by GET/POS method calls in the HTTP method.

## Common NAS (VPC) settings

The following describes commonly used request and response formats in NAS (VPC) APIs.

### Request

The following describes the common request format.

#### API URL

The request API URL is as follows:

```
https://ncloud.apigw.ntruss.com
```

### Request headers

The following describes the request headers.

| Field | Required | Description |
| --- | --- | --- |
| `x-ncp-apigw-timestamp` | Required | This is the number of milliseconds that have elapsed since January 1, 1970 00:00:00 UTC. - Request is considered invalid if the timestamp differs from the current time by more than 5 minutes. - Unix timestamp format. |
| `x-ncp-iam-access-key` | Required | Access key issued on NAVER Cloud Platform - Issue and check access key: See [Create authentication key](/docs/en/common-ncpapi#1%EC%9D%B8%EC%A6%9D%ED%82%A4%EC%83%9D%EC%84%B1). - Issue and check access key for sub account: See [Create sub account](https://guide.ncloud-docs.com/docs/en/subaccount-use#%EC%84%9C%EB%B8%8C-%EA%B3%84%EC%A0%95-%EC%83%9D%EC%84%B1). |
| `x-ncp-apigw-signature-v2` | Required | Base64-encoded signature that encrypts the request information with a secret key that maps to the access key issued on NAVER Cloud Platform, using the HMAC encryption algorithm (HmacSHA256). - Issue and check secret key: See [Create authentication key](/docs/en/common-ncpapi#1%EC%9D%B8%EC%A6%9D%ED%82%A4%EC%83%9D%EC%84%B1). - Create signature: See [Create signature](/docs/en/common-ncpapi#%EC%8B%9C%EA%B7%B8%EB%8B%88%EC%B2%98%EC%83%9D%EC%84%B1). |

### Response

The following describes the common response format.

#### Response status codes

NAS (VPC) APIs use NAVER Cloud Platform's common response status codes. For information about the HTTP status codes common to NAVER Cloud Platform, see [Ncloud API response status codes](/docs/en/common-ncpapi#3%EC%9D%91%EB%8B%B5%EC%83%81%ED%83%9C%EC%BD%94%EB%93%9C).
