The format of the API is https://connect.biorxiv.org/api/disqus/[interval]/[cursor]
where 'interval' can have a year value such as '2013' or 'all', for all years, and 'cursor' is the start point.
Results are paginated with 100 comments served in a call. The 'cursor' value can be used to iterate through the result.
For instance, https://connect.biorxiv.org/api/disqus/2013/10 will output 100 comments (if that many remain) with date of 2013 beginning from comment 10.
The 'messages' array in the output provides information about what is being displayed, including cursor value and count of items for the requested interval.
The default output format is JSON and CSV download is also available, eg https://connect_biorxiv.org/api/disqus/2013/10/csv.
'Interval' defaults to 'all' and cursor defaults to 0. https://connect_biorxiv.org/api/disqus/help serves this help screen.
