Crypta segments are available for behavioral targeting of display advertising:

• The RetargetingLists service supports using behavioral segments in audience targets based on user profiles.
• The Dictionaries.get method returns behavioral characteristics in the AudienceCriteriaTypes reference list and behavioral segments in the AudienceDemographicProfiles reference list.

The Dictionaries.get method also returns the minimum and maximum CPM bids for display ads  in the Currencies reference list.

Added restriction: in an “Ads for mobile apps” campaign, all ad groups must have the same app link.
