Yes. Both the ETL and the API supports Ad Revenue & Monetization data.
API Support:
The API supports aggregate level reporting and therefore supports the data available on the Ad Monetization Analytics Report. See the Ad Monetization API Reference.
ETL Support:
The ETL supports both aggregate level and user level data sets. You can reference the aggregate ad monetization data schema for the Ad Monetization report. You can find the user-level data schema for the Ad Revenue Attribution solution.
