The Additional Data service endpoint returns sets of coordinates that represent the outline of a city, country, or land area. The service supports batch requests of up to 20 identifiers.

HTTPS Method: GET

Generic URL format

GET https://<baseURL>/search/<versionNumber>/additionalData.<ext>?key=<Your_API_Key>&geometries=<geometryIds>&[geometriesZoom=<zoomLevel>]

curl command format

curl -XGET -H "Content-type: application/json" 'https://<baseURL>/search/<versionNumber>/additionalData.<ext>?key=<Your_API_Key>&geometries=<geometryIds>&[geometriesZoom=<zoomLevel>]'

Request Parameters

The following table describes the parameters that can be used in a Request.

• Required parameters must be used or the call will fail.
• Optional parameters, which are highlighted with [square brackets], may be used.
• If there is a default value that will be assumed when an optional parameter is not used, it is shown in the table.

Optional Parameter: [geometriesZoom]

Clients can use the optional [geometriesZoom] parameter to control the level of detail in the returned geometry data.

• Requests with lower zoom levels return less detailed geometries, which are also smaller in data size.
• If the [geometriesZoom] parameter is not provided, the level of detail for that given geometry will not be changed.
• See the following Table 1 for possible [geometriesZoom] values and their level of detail represented as precision.
• The [geometriesZoom] value is applied to all the geometries in the Response.

Response body

The Response will be a JSON object with the following structure:
