-NetBox paginates large result sets to reduce the overall response size. The [`MAX_PAGE_SIZE`](../configuration/miscellaneous.md#max_page_size) parameter specifies the maximum number of results per page that a client can request. This is set to 1,000 by default. Consider lowering this number if you find that API clients are frequently requesting very large result sets.

+Both pagination strategies support an optional `limit` parameter specifying the maximum number of objects to include in the response. The [`MAX_PAGE_SIZE`](../configuration/miscellaneous.md#max_page_size) configuration parameter (default `1000`) sets a hard ceiling on this value; if no limit is specified, up to `MAX_PAGE_SIZE` records are returned.
