# Statistics

This is an API for querying clinic operation data by item.

To protect personal information, personally identifiable data such as client name, phone number, and date of birth are not provided. Use `visitorChartNumber` (chart number) as the key for mapping clients to your clinic system.

<summary>Cursor-based Pagination</summary>

Definition: A method of retrieving large amounts of data in sequential pages

If `limit` is specified, the response will include `nextCursor`. Pass the `cursor` value as-is when requesting the next page. `totalCount` is only returned in the first response made without a `cursor`.
