Enroll recurring search or case-status observations within an explicit budget and expiry. First create_quote(action='monitor', input={rights_holder_id, work_id, delegation_id, target_action, expires_at, per_run_limit_cents, total_limit_cents, main_handle or case_id}). target_action='search' needs main_handle; 'status' needs case_id. cadence_hours defaults to 24. Returns monitor_id; each run reserves credits and pauses when funding, authority, expiry or limits disallow work. Never schedules takedown submissions. Authenticate with the matching action scope. Reserves the quoted maximum from prepaid credits and returns operation_id; poll get_operation for results. Sandbox execution is simulated.
