What is VOUCH?

You run an AI agent. It makes decisions: approve a loan, flag fraud, moderate content, send an email. Good. Now your boss, your regulator, your customer asks: What exactly did it do? How do I know it followed my rules?

VOUCH is your answer. Every decision your agent makes gets a cryptographic proof. It's tamper-proof, verifiable, and audit-ready. You can show auditors, regulators, or customers exactly what happened.

Three lines of code. Call our API. Get back a proof. Show it to anyone. That's it.
