API to pull all news post from sharepoint online site

Hey roshan08 

You can use SharePoint Search API to fetch all the news pages from specific sites as below

https://xxx.sharepoint.com/_api/search/query?querytext='SPContentType:"Site Page" AND IsDocument:True AND FileExtension:aspx AND PromotedState:2 AND FirstPublishedDate=today AND  Path:https://xxx.sharepoint.com/sites/xxx OR Path:https://xxx.sharepoint.com/sites/xxx OR Path:https://xxx.sharepoint.com/sites/xxx/SitePages'&sortlist='FirstPublishedDate:descending'&startRow=0&rowlimit=100&selectproperties='Title,Description,RefinableString03,FirstPublishedDate,PictureThumbnailURL,WebId,Path'

There is a possibility to use Graph API as well that you may try it.

Thanks,

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=*

roshan08 Any particular reason you need an api? A simple flow in Power Automate can do this easily.
