Last activity date

Question

It would be useful if the API allowed you to return items based on their last activity date. Let's take a question for example.

/questions/fromlastactivitydate=XYZ&tolastactivitydate=XYZ

All questions having been created, edited, commented on or answered on as their last activity during the requested period would be returned.

There is already a last-activity field returned in the API, so I assume it would be a trivial concept to implement. It would be great if that could also be applied to Users as well.

The returned values should only include the activities that took place during that period of time, for example, only comments and answers that have been made during the requested period.

A possibly more complex, but related, query would be to provide an activity period, which doesn't have to be the last activity date of a question, and the returned values would be all questions which had activity during said period and including only answers/comments that were made during that period.

Answer 1

Anything that supports a sort of activity can do this already.

?sort=activity&min={start-date}&max={end-date}

Where start-date and end-date are unix timestamps.

Update

/questions and /questions/unanswered now honor min, max, and order.

sort     | min and max limit
--------------------------------
active   | last_activity_date
newest   | creation_date
featured | bounty_closes_date*
hot      | last_activity_date
week     | last_activity_date
month    | last_activity_date
votes    | score

todate and fromdate, as always, limit creation_date.

_{*bounty_closes_date is always in the future, as featured only returns those questions whose bounties haven't passed yet.}
