The Problem

Your clients need
proof, not promises

If your agency generates AI content for banking, pharma, insurance, or legal clients — compliance isn't a feature. It's a contract requirement.

EU AI Act Art. 50

From August 2026, every AI-generated output must be machine-readable marked. No exceptions for agencies.

Regulated clients demand audit trails

Banking & pharma compliance officers need documented, verifiable proof of content origin for every campaign.

Databases can be tampered

Centralized logs require trust in the operator. Regulators need independent, third-party verification.

AI agents need trust infra

Autonomous agents generating content 24/7 need cryptographic AI compliance — no human in the loop.

How It Works

Three calls.
Full AI Compliance.

Integrate in 20 minutes. Certify every piece of AI content. Hand clients a verification link they can forward to auditors.

Step 01

Certify

Hash + metadata → immutable Base L2 record + C2PA Content Credential. Returns certificate ID and public verify URL.

POST /v1/certify
Step 02

Verify

Public endpoint. No API key. No account. Anyone — regulators, auditors, clients — can verify any certificate independently.

GET /v1/verify/{id}
Step 03

Audit

Enterprise dashboard. All certs, compliance reports, content type breakdown. Exportable PDF/CSV. GRC webhook integration.

GET /v1/audit
certify_pharma_content.py
import vottun_ai_compliance

client = vottun_ai_compliance.Client("vt_live_...")

# Certify AI-generated marketing copy for regulated client
cert = client.certify(
    content=blog_post_html,
    content_type="text/html",
    ai_system="claude-sonnet-4-5",
    classification="fully_ai_generated",   # EU AI Act content type
    metadata={
        "client": "Pharma Corp",
        "campaign": "Q1 Product Launch",
        "deployer": "agency-name"
    }
)

print(cert.verify_url)    # → https://verify.vottun.com/c/0x7f3a...
print(cert.tx_hash)       # → Base L2 transaction hash
print(cert.c2pa_manifest)  # → C2PA Content Credential JSON

x402 Protocol

Machine-to-machine
AI compliance

AI agents with a USDC wallet certify content autonomously. HTTP 402 → payment → certificate. No humans. No API keys. Wallet is identity.

The x402 protocol (Cloudflare + Coinbase) enables machine-to-machine HTTP payments. Your AI agent generates content, calls the certification endpoint, pays €0.01–0.02 USDC from its wallet on Base L2, and receives an immutable AI compliance record — all in under 4 seconds.

autonomous_agent.py
# AI agent self-certifies via x402
response = requests.post(
    "https://api.vottun.com/v1/certify",
    headers={
        "X-402-Payment": usdc_proof,
        "X-Agent-Wallet": "0x..."
    },
    json={
        "content_hash": sha256,
        "ai_system": "agent-v2",
        "classification": "fully_ai_generated"
    }
)
# No API key — wallet IS the identity
x402 Certification Flow
01
Agent generates content via Claude, GPT, DeepSeek, or any model.
02
Calls POST /certify — receives HTTP 402 with USDC payment instructions.
03
Sends USDC from its Base L2 wallet. Confirms in ~2 seconds.
04
Retries with payment proof. Certification anchored on-chain. C2PA credential returned.
05
Content is AI compliance-certified. Verifiable by any human or machine via GET /verify.
