Is it possible to request the check_list_id of a specific place, or group of places using the /places.json, or other, endpoint? This isn’t available from any of the v1 Places API endpoints.
https://www.inaturalist.org/places/1.json :
{
"id": 1,
"name": "United States",
"display_name": "United States",
"code": "US",

"updated_at_utc": "2018-09-06T14:34:21.635Z"
}
that’s more difficult. best approach probably depends on the specific places and how they are related to each other or not.
