Hi Victor,
The Data Feed Query Explorer link I posted previously uses the newer api, so it may return different results.
Using the Query Editor include in In Site Analytics, I created a query with the same data as the top content for todays traffic and it shows the same data for my site as the report except for small differences due to timing. The report gets cached for 10 minutes I think whereas the query is live.
For Metrics I put:
ga:pageviews,ga:visits,ga:newVisits,ga:entrances,ga:bounces
For Dimensions I put:
ga:pagePath
For Sort I put:
-ga:pageViews
For Date Mode set "Use Specific Dates"
For both dates put 02/21/2012
For Max Rows to get put 50
Best,
Joe
