Is there an equivalent type on Server to the type returned from GET /rest/api/3/field on Cloud?

The Cloud endpoint GET /rest/api/3/field returns something like:

    "id": "statuscategorychangedate",
    "key": "statuscategorychangedate",
    "name": "Status Category Changed",
    "custom": false,
    "schema": {
      "type": "datetime",
      "system": "statuscategorychangedate"
    "navigable": true,
    "orderable": false,
    "searchable": true,
    "clauseNames": [

The com.atlassian.jira.issue.fields.FieldManager component returns various children of Field but none of them look like that when serialized, for example Field has nameKey instead of key.

Is there another Manager class I can use to get the same data type returned by cloud for issue field configuration?
