How do I govern billable calls from AI agents in a government and public sector environment?

Route billable calls through Kastra. The Kastra proxy or SDK intercepts each request before it executes, evaluates ABAC policy against the request attributes, environment, principal identity, and risk signals, and returns an allow, deny, redact, or human-approval decision. Government and public sector customers map controls directly to FedRAMP, FISMA, CJIS, IL5.
