I have a folder in my Google Reader account called Test, with 200 items in. I only want to collect 20 items at a time.
According to the docs I can add ?n=20 or ?count=20 to the url to get the first 20 items. But when I use this link http://www.google.com/reader/atom/user/-/label/Test?count=20 or http://www.google.com/reader/atom/user/-/label/Test?n=20 I get all 200.
Try this one.
https://www.google.com/reader/api/0/stream/contents/user/-/label/Test?ot=[epoch time]&r=a&xt=user/-/state/com.google/read&n=20&ck=[epoch time]&client=web
ot= is the time of the oldest article you want. time-(day*86400) r= sort order a=magic n=desc o=asc xt= what to exclude, the above excludes read articles, blank returns everything. n= the number of articles to return ck= not really sure, I put in the current epoch time and it works client= string to identify client used.
