Given a valid address or video ID, the
[`lookupVideo`](https://developers.google.com/maps/documentation/aerial-view/reference/rest/v1/videos/lookupVideo.md.txt)
method returns URIs identifying a set of Aerial View API videos. The
`lookupVideo` method only returns URIs when Google has already generated a video
for that location.

To check if a video exists, use the
[`lookupVideoMetadata`](https://developers.google.com/maps/documentation/aerial-view/lookup-video-metadata.md.txt)
method.

> [!NOTE]
> **Note:** After Google generates an aerial video for a specific address, that video is available to anyone. That is, a video is not associated with a specific user or account.

## How to use the API

Call this endpoint by passing it a [URL-encoded](https://developers.google.com/maps/url-encoding.md.txt) U.S. postal
address or a
[`videoId`](https://developers.google.com/maps/documentation/aerial-view/reference/rest/v1/VideoMetadata.md.txt).

```json
curl -X GET "https://aerialview.googleapis.com/v1/videos:lookupVideo?X-Goog-Api-Key=YOUR_API_KEY&address=POSTAL_ADDRESS"
```

The API then returns one of the following three responses:

- If a video exists, `lookupVideo` returns a processing state of `ACTIVE`, and
  a landscape and a portrait URI for every supported media type, and
  [metadata](https://developers.google.com/maps/documentation/aerial-view/reference/rest/v1/VideoMetadata.md.txt).

  > [!NOTE]
  > **Note:** Calls to this endpoint are billed only when a video exists and a video URI is returned.

- If the video is in our system, but it still hasn't been fully rendered,
  `lookupVideo` returns a processing state of `PROCESSING`, and a `videoId`,
  which you can use to get the video after it's done rendering.

- If the video doesn't yet exist, then the API returns a 404 status code. In
  this case, you can [generate a new video](https://developers.google.com/maps/documentation/aerial-view/generate-video.md.txt) by calling
  [`renderVideo`](https://developers.google.com/maps/documentation/aerial-view/reference/rest/v1/videos/renderVideo.md.txt).

## How to use the returned video URIs

Call the `lookupVideo` method once per address or `videoID` per view. The video
URIs in the response are referred to as *short-lived URIs* and expire after a
short time.

Google frequently updates the videos. Therefore, to ensure that you are
displaying the latest content to your customers, call the `lookupVideo` method
every time you display a video.

> [!CAUTION]
> **Caution:** You cannot download, store, or cache the aerial view videos. For more information, see the [Google Maps Platform Terms of
> Service](https://cloud.google.com/maps-platform/terms/).

### Supporting accessible videos

To support accessibility, Google recommends that you add a transcript or video
description when you display an aerial view video to your customers. In that
way, a screen reader can announce the transcript or its description to a user.

For example, add a description in the form:

"This is a photorealistic aerial view of **ADDRESS** provided by Google Maps."

Instead of an address, you could add a description of the video, in the form:

"This is a photorealistic aerial view of the Empire State Building in New York
provided by Google Maps."

## Save video IDs for later use

Subject to the Service Specific Terms for Aerial View API, Aerial View API
video IDs are **exempt from** the caching restrictions stated in
[Section 3.2.3(b)(No Caching)](https://cloud.google.com/maps-platform/terms/)
of the Google Maps Platform Terms of Service. You can therefore store
video ID values for later use.

## Example request passing an address

The following code sample requests an aerial view video for the Transamerica
Pyramid, located at 600 Montgomery St, San Francisco, CA 94111.

```json
curl -X GET "https://aerialview.googleapis.com/v1/videos:lookupVideo?X-Goog-Api-Key=YOUR_API_KEY&address=600%20Montgomery%20St%2C%20San%20Francisco%2C%20CA%2094111"
```

> [!NOTE]
> **Note:** You must [URL encode](https://developers.google.com/maps/documentation/aerial-view/web-api-best-practices.md.txt#BuildingURLs) the address.

## Example response

The following JSON examples represent all possible responses to the
`lookupVideo` request.

### Video found

If the video you're requesting exists, the API returns a list of URIs, each
of which links to a different format or version of the requested video. To learn
about the various formats, see
[What is MPEG-DASH? \| HLS vs. DASH](https://www.cloudflare.com/learning/video/what-is-mpeg-dash/).

> [!NOTE]
> **Note:** Call `lookupVideo` once per address or `videoID` per view. You can then use the short-lived URIs in the response once before they expire.

To access videos, you must allowlist the following domains:

- `*.gstatic.com`
- `*.googlevideo.com`

### Video not found

There are two possible "Video not found" responses, depending on whether or not
3D imagery is available for the location.

#### Not rendered

The video hasn't been previously rendered, and therefore is not yet in Google's
database.

```json
{
  "error": {
    "code": 404,
    "message": "Video not found.",
    "status": "NOT_FOUND"
  }
}
```

#### No 3D imagery

Google attempted to render the video already, but failed because 3D imagery
isn't available for that address.

```json
{
  "error": {
    "code": 404,
    "message": "Video not found: No 3d imagery.",
    "status": "NOT_FOUND"
  }
}
```

### Rendering in progress

The system is still processing your render request, as defined by the `state`
being set to `PROCESSING`. You get a `videoId`, which you can then use to get
the video by calling `lookupVideo`.

```json
{
  "state": "PROCESSING",
  "metadata": {
    "videoId": "u-zlVPiScvcD8BYmIVyxoF"
  }
}
```

The rendering process can take anywhere from an hour to a few hours. If the
video is still processing, you can use `lookupVideo` to poll the video status
until it returns a state of `ACTIVE`.

To poll, make a request to `lookupVideo`, passing the `videoId`. Rendering can
take several hours, so use
[exponential backoff](https://developers.google.com/maps/documentation/aerial-view/web-api-best-practices.md.txt#exponential-backoff)
to space out your calls.

## Example request passing a `videoId`

If you call `lookupVideo` and discover that there is no aerial view video
for the address, then you can call `renderVideo` with that address.
`renderVideo` returns a
[`VideoMetadata`](https://developers.google.com/maps/documentation/aerial-view/reference/rest/v1/VideoMetadata.md.txt)
object, which contains the `videoId`. You can later use the `videoId`, rather
than an address, to get the video by passing it to `lookupVideo`.

The following code example demonstrates how to call `lookupVideo`, passing it a
`videoId`.

```json
curl -X GET "https://aerialview.googleapis.com/v1/videos:lookupVideo?X-Goog-Api-Key=YOUR_API_KEY&videoId=VIDEO_ID"
```
