Magento2: getting full image URL from rest API: /V1/products/(productID)/media

[userException]

http://mymagentohost.com/index.php/rest/V1/products/(productID)/media

This url is used to get the media for a particular product.

The response does not have the full image URL.

Response:

{
"id": 14,
"media_type": "image",
"label": "",
"position": 1,
"disabled": false,
"types": [
"image",
"small_image",
"thumbnail"
],
"file": "/p/w/pwp_sheet2.jpeg"
}
I am trying to access this URL from a ios app.

@userException You have the BASE URL because you access the API. Or i'm wrong?

[userException]

but what should be the prefix for this URL ? if I want to download this image and show this in my app

Within Magento, you can use \Magento\Catalog\Model\Product\Media\Config::getBaseMediaUrl() to access the media base URL. However, since you are in an app, you will probably have to hardcode the prefix.
If the Webserver document root is configured to the pub/ directory within Magento, the media base URL for you would be http://mymagentohost.com/media/catalog/product.
If the Webserver document root is configured to the Magento base directory, the media base URL for you would be http://mymagentohost.com/pub/media/catalog/product.

Use the storeConfig API to get the base media url - http://devdocs.magento.com/swagger/index.html#!/storeStoreConfigManagerV1/storeStoreConfigManagerV1GetStoreConfigsGet
