How do I govern billable calls from AI agents in a biotech and pharma 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. Biotech and pharma customers map controls directly to 21 CFR Part 11, GxP, HIPAA.
