The code block below demonstrates a complete request for the public transit stop.

The response to the request delivers the following JSON object.

{ "metadata" : {
"street labels":[ ... ],
"city center labels":[],
"buildings":[ ... ],
"transit stops":[ { "name": "Stadtmitte", "bounding boxes": [ { "box 1":[ 136.50, 177.02, 14, 14 ] }, { "box 2":[ 113.22, 163.02, 60.56, 13 ] } ], "info": [ { "position": {"latitude":52.510475, "longitude":13.389920}, "official name": "Stadtmitte", "places id": "721680928", "operating hours": { "Monday":[["0:0:0","24:0:0"]], "Tuesday":[["0:0:0","24:0:0"]], "Wednesday":[["0:0:0","24:0:0"]], "Thursday":[["0:0:0","24:0:0"]], "Friday":[["0:0:0","24:0:0"]], "Saturday":[["0:0:0","24:0:0"]], "Sunday":[["0:0:0","24:0:0"]], "Holiday":[["0:0:0","24:0:0"]] }, "parking hours": { "Monday":[["0:0:0","24:0:0"]], "Tuesday":[["0:0:0","24:0:0"]], "Wednesday":[["0:0:0","24:0:0"]], "Thursday":[["0:0:0","24:0:0"]], "Friday":[["0:0:0","24:0:0"]], "Saturday":[["0:0:0","24:0:0"]], "Sunday":[["0:0:0","24:0:0"]], "Holiday":[["0:0:0","24:0:0"]] } } ]} ],
"POIs":[  ]
Out of this object there following properties are of interest to get the geo location:
  • places id: contains the places identifier of the transit stop
  • operating hours: contains an array of days and times when the public transit stop operates
  • parking size: contains the parking size (if applicable)
  • parking hours: contains the allowed parking hours (if applicable)
Note: Please note this additional information might not be included when it is not available, so the response might be shorter than what is shown in the example.

Although it is not easy to find locations at the moment that contain places id as a property, the coverage is growing. Mainly the locations in the US contain places id. See example below of a public transit stop in Chicago.
