Response

{
  "object": "list",
  "has_more": false,
  "data": [
    {
      "object": "contact_property",
      "id": "b6d24b8e-af0b-4c3c-be0c-359bbd97381e",
      "key": "company_name",
      "type": "string",

  ]
}

has_more tells you whether another page exists — there is no total, because a keyset paginator never counts the table. To walk every page, pass the last id you saw as after until has_more is false. See Pagination.
