Revised request of https://phabricator.wikimedia.org/T133176 based on a discussion on IRC.
The hope is to have the topviews endpoint allow a week parameter for the given year, where you would then leave month and day blank.
This request stems from the fact that The Signpost, a highly visible publication for the English Wikipedia, is still using the less accurate data dumps for their weekly traffic report.
I have created Topviews Analysis which allows you to put in an arbitrary date range (max one month), but there's the caveat in that the numbers you see are summations of the top views for each individual day. This means if a given page was not in the top 1000 within that date range, the total number of pageviews will be off.
Also mind you we wouldn't object to a limit parameter, should that help with performance. We generally are only interested in the 100 pages or so. I understand this top views data is precomputed in Cassandra, so perhaps a limit option wouldn't help, but throwing it out there just in case.
