# Sitemap operations
Sitefinity’s OData web services expose a single endpoint that allows querying data from Sitefinity CMS sitemap. Such data can be used to construct navigation widgets. The navigation widget in Sitefinity ASP.NET Core renderer uses this endpoint.
> **IMPORTANT**: The following endpoint is designed to support ASP.NET Core development only. You cannot use the endpoint for MVC development.\
> For a comparison on using ASP.NET Core vs using MVC framework, see [Development comparison](https://www.progress.com/documentation/sitefinity-cms/mvc-or-.net-frontend---a-comparison).
> info **NOTE**: This endpoint does not require authentication.
To use the endpoint, execute a `POST` request to the following endpoint:
`{baseurl}/api/default/pages/Default.HierarhicalByLevelsResponse()`
**Sample request**
> success **POST** `http://mysite.com/api/default/pages/Default.HierarhicalByLevelsResponse()`
**Sample response**

There are query parameters that can be added to this request. For example:
* `selectionModeString`can have one of the following values:
* `TopLevelPages`\
This will force the request to take only the root level pages’ data. This is the default case.
* `SelectedPages` works in conjunction with `selectedPages` to take only the explicitly stated pages’ data.
* `CurrentPageSiblings` works in conjunction with `sf_page_node`.\
It returns only the data for the sibling pages of the currently targeted page by the `sf_page_node` parameter.
* `CurrentPageChildren` works in conjunction with `sf_page_node`.\
It returns only the data for the child pages of the currently targeted page by the `sf_page_node` parameter.
* `SelectedPageChildren` works in conjunction with `selectedPageId`.\
It returns only the data for the child pages of the currently targeted page by the selectedPageId parameter.
* `showParentPage` shows information about the parent page.\
This parameters is a `Boolean`.
* `selectedPageId` returns the `GUID` of a page node.
* `selectedPages` returns the `GUID` array of page node IDs.
* `sf_page_node` returns the `GUID` of a page node.
The following example uses some of the above query parameters:
