1. Where are you trying to pull the news posts, SPFx or Power Automate/Apps or anywhere else?
2. What information related to news posts do you need, page name/other column values, etc.?

You can use generic SharePoint REST API like below to get the page items from Site pages library: 

<siteUrl>/_api/Web/Lists/getByTitle('Site Pages')/items?$select=*
