Useful for charging for things like queries, searches, or success events (success-based pricing). Here's how it works:

• Set up event-based features to be bill per use, e.g. $0.05 per query
• Build plans that include usage-based charges
• Users can buy plans with usage-based charges and monitor usage in the Schematic component
