Facebook recently announced it is possible to retrieve statistics on the new Send Button via the Graph API.  The statistics currently available are only for the domain as a whole - not a particular page.  These include domain_widget_send_views, domain_widget_send_clicks, domain_widget_send_inbox_views, and domain_widget_send_inbox_clicks.  However, if you list the statistics available for your app (https://graph.facebook.com/APP_ID/insights?access_token=xxxxxxx), you won't see domain_* statistics listed.

Your domain has a different object_id in the Graph API than your app.  In order to get the object_id for your domain, you can use the domain FQL table: https://developers.facebook.com/docs/reference/fql/domain/  You can also use a little trick if you have already claimed the domain at https://facebook.com/insights.  You can claim domains that have fb:app_id open graph tags at the root of the domain (i.e. http://www.your-domain.com/) where you have been given at least Insights access for the app.

If you see a claimed domain listed in the websites section of https://facebook.com/insights, the "View Insights" link will take you to a url like this: https://www.facebook.com/insights/?sk=wo_###########  That number after https://www.facebook.com/insights/?sk=wo_ is the object_id of your domain.  You can confirm that via this url: https://graph.facebook.com/DOMAIN_OBJECT_ID?metadata=1

Once you have the domain object id, you can now get the domain insights including the new Send Button data via https://graph.facebook.com/DOMAIN_OBJECT_ID/insights?access_token=xxxxxxx. If you need to obtain an access token, the Graph API Explorer tool makes it easy. Click on "Get Access Token" and then check off "read_insights" from the Extended Permissions tab.
