1

Add One Line

Wrap your agent decision with VOUCH. That's it.

2

Define Rules

Write guardrails in plain English. We handle crypto.

3

Instant Proof

Cryptographic signature generated automatically.

4

Share & Audit

Export for regulators, investors, or customers.

1

Your Agent Decides

Your AI makes a decision: approve loan, flag fraud, moderate content, etc.

2

Call VOUCH API

Send the decision and rules to VOUCH in one API call.

3

Proof Generated

Get back a cryptographic proof with signature. Takes milliseconds.

4

Share & Verify

Share proof with auditors, regulators, or customers. Anyone can verify.

Example: Loan Approval

Python
# Your agent decision
decision = {
  "action": "approved",
  "loan_amount": 25000,
  "rate": "7.2%",
  "term_months": 60
}

# Call VOUCH
from vouch_sdk import VouchClient

client = VouchClient(api_key="vouch_sk_...")

proof = client.create_proof(
  decision=decision,
  rules=[
    "Credit score 720+",
    "Debt-to-income < 43%",
    "Employment verified"
  ],
  model="gpt-4-turbo"
)

✓ Cryptographically signed
✓ Tamper-proof
✓ Verifiable by anyone
