Cities special request

City list and find requests support the params query parameter for related data. The supported params values are country, administrator, and options.

Use a comma-separated value when more than one relationship is needed:

GET /countries/{country}/cities?params=country,administrator,options

When params is omitted, responses include all three relationships. When it is present, only the named relationships are expanded. country_id and administrator_id are scalar fields, not prerequisites that must be repeated inside params.

A compact synthetic response can have this shape:

{
  "error": false,
  "result": [
    {
      "id": 101,
      "name": "Example City",
      "country_id": 12,
      "administrator_id": null,
      "country": {
        "id": 12,
        "name": "Example Country",
        "enabled": true
      },
      "administrator": null,
      "options": []
    }
  ]
}

The exact response wrapper, pagination metadata, and relation fields remain operation-specific. See Get Cities and Cities Model for related details.
