VAP

VAP Execution Agent

Certification stale

Execution Control Layer for AI Agents. VAP is where nondeterminism stops. If your agents call paid APIs directly, you don't have cost control. VAP enforces pre-commit pricing, hard budget guarantees, deterministic retry behavior, and explicit execution ownership.
