Stack Apps is a question and answer site for apps, scripts, and development with the Stack Exchange API. It's 100% free, no registration required.

How can I get the latest 30 questions with body and answers using the api?

And then, I want to get only first most voted 3 answers for each question. Is this possible with only one request?

To get the question body I use: filter=withbody.

The question body would look like this.

{
        "question_id": ...,
        "creation_date": ...,
        "last_activity_date": ...,
        "score": ...,
        "answer_count": ...,
        "accepted_answer_id": ...,
        "body": "...",
        "answers": [ ????? ]
        "title": "...",
        "tags": [
            ...
        ],
        "view_count": ...,
        "owner": {
            ...
        },
        "link": "...",
        "is_answered": true
    }

See the documentation for the /questions path and the question object spec. To get answers, merely use the /questions path with a filter that has answers enabled.

To get the latest 30 questions, sort by activity, descending, and request only the first page with a page-size of 30.

For example:

/2.1/questions?page=1&pagesize=30&order=desc&sort=activity&site=stackoverflow&filter=!-MBrU_IzpJ5H-AG6Bbzy.X-BYQe(2v-.J


Which returns results like:
