The Children Lookup query allows you to submit the Placekey of a location and get the children back in a Basic Place Response.

This query supports pagination and requires Nesting Place Responses.

In this example, we're requesting all of the child POI of the placekey for the Denver Airport.

{
  childrenLookup(placekey: "zzw-222@5qk-kb7-7wk")
  {
    places {
      locationName
      placekey
      address {
        streetAddress
        city
