Currently the AreaButler Census-Atlas API supports the search of the existing Census Atlas indices around a certain point. The point could be specified either by providing its coordinates or the known address.

The GET request should be sent to fetch the indices:

Parameters:
  Mandatory:

    // OR
    lat=51.2265311&lng=6.7842183

The response contains the following body:

{
  "input": {
    "coordinates": {
      "lat": 51.2265311,
      "lng": 6.7842183
