Cursor from `page.nextCursor` of the previous response. Start without one; a page can be empty while `page.hasMore` is true, so keep following it. It only works for the same `modifiedSince` filter.

Profiles per page, 1 to 500. Default: 100.

Only profiles last modified at or after this time, as an ISO 8601 date or time (such as `2026-01-31`) or epoch seconds; no zone means UTC. A page can be empty while `page.hasMore` is true; follow `page.nextCursor`.
