Fetch the content of the confluence KB articles using REST API

We are trying to fetch the content of confluence articles via REST API -

So far I have tried the following api but I am not able to retrieve all the contents present on that particular page:

https://id.atlassian.net/wiki/rest/api/content/{page_id}?expand=body.storage

Is there a better way to fulfil the requirement to fetch the contents of a particular space using the REST API?

Thanks,

Kompal

Solution found, the above mentioned API is correct
