This section covers a series of example requests to the Places Aggregate API.

## Client library installation

To use the Python (gRPC) examples, you must install the specific client library
for the Places Aggregate API and the Google Auth library:

```bash
pip install google-maps-areainsights google-auth
```

## Return places within a circle

Return all restaurants within a 200m radius of Trafalgar Square, London.

- The search area is a circle centered on a specific latitude and longitude. The radius of this circle is 200 meters, which determines the size of the search area.
- The [place type](https://developers.google.com/maps/documentation/places/web-service/supported_types) requested is restaurant, and this is passed using `includedTypes` within `typeFilters`.
- The count is requested using `INSIGHTS_COUNT`, and the [place IDs](https://developers.google.com/maps/documentation/places/web-service/place-id.md.txt) are requested using `INSIGHTS_PLACES`.

### Rest

```bash
curl --location 'https://areainsights.googleapis.com/v1:computeInsights' \
--header 'X-Goog-Api-Key: API_KEY' \
--header 'Content-Type: application/json' \
--data '{
  "insights": ["INSIGHT_COUNT", "INSIGHT_PLACES"],
  "filter": {
    "locationFilter": {
      "circle": {
        "latLng": { "latitude": 51.508, "longitude": -0.128},
        "radius": 200
      }
    },
    "typeFilter": { "includedTypes": "restaurant" }
  }
}'
    
```

### Python (gRPC)

```python
from google.maps import areainsights_v1
from google.maps.areainsights_v1.types import (
    ComputeInsightsRequest,
    Filter,
    LocationFilter,

)
from google.type import latlng_pb2
from google.oauth2 import service_account

def get_area_insights():
    # Initialize the client
    credentials = service_account.Credentials.from_service_account_file(
        'path/to/service_account.json',
        scopes=['https://www.googleapis.com/auth/cloud-platform']
    )
    
    client = areainsights_v1.AreaInsightsClient(

            lat_lng=lat_lng,
            radius=200
        )
    )

        included_types=["restaurant"]
    )

    # Create the main filter
    filter = Filter(
        location_filter=location_filter,
        type_filter=type_filter
    )

    # Create the request
    request = ComputeInsightsRequest(
        insights=[
            Insight.INSIGHT_COUNT,
            Insight.INSIGHT_PLACES
        ],
        filter=filter
    )

    try:
        # Make the request
        response = client.compute_insights(request=request)
        
        # Print results
        print(f"Total count: {response.count}")
        print("\nPlaces found:")
        for place in response.place_insights:
            print(f"Place ID: {place.place}")

    except Exception as e:
        print(f"Error occurred: {e}")

if __name__ == "__main__":
    get_area_insights()
  
```

## Exclude place types

You can exclude place types from the count.

The following request is the same as the first example, but adds
`excludedTypes` to the `typeFilters`. You can use either a string or an array
of strings for the `includedTypes` and `excludedTypes`.

This example excludes two place types: `cafe` and `bakery`, from the
`restaurant` count.

## Use primary type

This example modifies the request from the first example to include only places
that have a `primaryType` of `restaurant` in the count.

## Custom polygon

This example demonstrates how to use a custom polygon to define your search
area. Keep in mind that specifying `INSIGHTS_PLACES` restricts the search to
areas small enough to return up to 100 place IDs. For larger areas, use
`INSIGHTS_COUNT` to bypass this limitation so that the service won't need to
return individual place IDs.

As before, the place type used is `restaurant`. This example also introduces
three other filters:

- `operatingStatus`: This example counts only operational places.
- `priceLevel`: This example counts only inexpensive and moderately priced places.
- `ratingFilter`: This example counts only places with a review score between 4.0 and 5.0.

## Geographical area

This example uses a [Geographical Area](https://developers.google.com/maps/documentation/places/web-service/place-types.md.txt#geographical-areas) place ID to set the search area.
These place IDs include the geometry of a place, such as a town or city. The
place ID used here is `ChIJiQHsW0m3j4ARm69rRkrUF3w`, which corresponds to the
city of [Mountain View, California](https://maps.app.goo.gl/WKQkwbGrsFgi55Gn9).

Passing the place ID to the Places Aggregate API sets the search area to the bounds
of the geographic area. The place ID is passed using `place`, in the format
`places/place_ID`.

You can obtain a Geographical Area place ID in any of the following ways:

- [Place ID Finder](https://developers.google.com/maps/documentation/javascript/examples/places-placeid-finder.md.txt)
- [Geocoding API](https://developers.google.com/maps/documentation/geocoding/requests-geocoding)
- [Text Search (New)](https://developers.google.com/maps/documentation/places/web-service/text-search.md.txt)
- [Nearby Search (New)](https://developers.google.com/maps/documentation/places/web-service/nearby-search.md.txt)
- [Address Validation API](https://developers.google.com/maps/documentation/address-validation)
- [Place Autocomplete](https://developers.google.com/maps/documentation/places/web-service/place-autocomplete.md.txt)
