How can I get actual content of Page, Blogpost and Comments using Confluence Cloud REST API?

To get the actual content I tried using Get Content by Id API : https://{{host}}/wiki/rest/api/content/:id?expand with providing value for expand parameter as body.view, body.storage, body.styled_view, in response it give data as value to body key however it returns data as html form.

For attachment using Get Attachments API : https://{{host}}/wiki/rest/api/content/:id/child/attachment? it returns, _links object with webui, download key value in response, using which we can get actual content for attachment.

Please help to get actual content of Page, Blogpost and Comments using Confluence Cloud REST API.

Thanks in advance.
