Here is the Contract for Palantir's Super API for the IRS

Palantir delivered an API for the IRS Criminal Investigation division to integrate disparate financial systems. The API allows any app to access IRS data under the CI's oversight. Palantir is building a unified system to investigate financial crime. The initiative uses public records requests to validate access and data flow. The system connects legacy IRS databases into one investigative platform. This enables real-time cross-system analysis of financial transactions.
