Payment Infrastructure

AI governance for payment decisions.

AI agents are making authorization decisions, fraud determinations, and routing choices inside payment infrastructure. Kevros governs the agent's decision before it reaches the payment rail — producing cryptographic evidence of every action.

The problem

Payment protocols verify the handshake. Nobody governs the decision that led to it.

Visa TAP verifies transaction authenticity. Mastercard Verifiable Intent confirms payer consent. Google AP2 standardizes credential exchange. These protocols secure the payment rail itself.

But upstream of every payment rail, an AI agent decided to initiate that transaction, approve that authorization, flag that fraud case, or route that settlement. Who governed that decision? What evidence exists that the agent was authorized to act?

Kevros governs the agent decision layer — complementary to payment rail protocols, not a replacement for them.

How Kevros helps

Governance enforcement before the payment rail.

Pre-Rail Decision Enforcement
Every AI-initiated payment action is evaluated against governance policies before it reaches the processor, network, or settlement system. ALLOW, CLAMP, or DENY — enforced at decision time.
Cryptographic Evidence Chain
Hash-chained provenance ledger records every agent decision with tamper-evident integrity. Auditors verify the chain independently without access to your systems.
Formally Verified Enforcement
The governance kernel is exhaustively verified via TLA+ across 32.8 million state configurations. Zero safety violations found across all reachable states.
Model and Rail Agnostic
External governance works regardless of AI provider or payment processor. Agent governance remains consistent across model swaps, processor changes, and network migrations.
Behavioral Drift Detection
Behavioral confidence scoring detects when agent decision patterns change from established baselines. Alerts surface before drift reaches enforcement thresholds.
Per-Decision Provenance
Each governance decision generates a cryptographic receipt linked to the evidence chain. Every authorization, every routing decision, every fraud determination — individually verifiable.

Payment infrastructure use cases.

AI Authorization Agents
Govern AI agents that make real-time authorization decisions — approve, decline, or flag for review. Every decision carries cryptographic evidence of policy evaluation before reaching the network.
Fraud Detection Agents
Enforce governance on AI-driven fraud detection and transaction monitoring agents. Evidence trail for every flag, escalation, and hold decision made by autonomous systems.
Agentic Commerce
AI agents initiating purchases, managing subscriptions, and executing recurring payments on behalf of users. Governance ensures every agent-initiated transaction was authorized within defined boundaries.
Settlement and Routing
Govern AI agents that optimize payment routing, batch settlements, and cross-border transactions. Every routing decision and settlement action produces verifiable evidence.

Authorization Agent — Verify Before Deciding

from kevros_governance import GovernanceClient client = GovernanceClient(agent_id="auth-agent-001") # Verify authorization before the agent makes a decision result = client.verify( action_type="authorize_transaction", action_payload={ "merchant_category": "5411", "amount": 2847.50, "currency": "USD", "risk_score": 0.23, }, agent_id="auth-agent-001", policy_context={ "max_values": {"amount": 10000.00, "risk_score": 0.80}, }, ) if result.decision.value == "ALLOW": proceed_with_authorization(token=result.release_token) elif result.decision.value == "CLAMP": proceed_with_authorization( token=result.release_token, params=result.applied_action, ) elif result.decision.value == "DENY": decline_and_log(result)

Full Governance Loop — Agent Payment With Provenance

from kevros_governance import GovernanceClient, IntentType client = GovernanceClient(api_key="kvrs_your_key_here") # 1. VERIFY — Is this agent authorized to initiate payment? verify = client.verify( action_type="initiate_payment", action_payload={"amount": 500.00, "currency": "USD"}, agent_id="commerce-agent-003", ) # 2. BIND — Declare intent and bind to the payment action bind = client.bind( agent_id="commerce-agent-003", intent_type=IntentType.AI_GENERATED, intent_description="Process subscription renewal payment", command_payload={"amount": 500.00, "currency": "USD"}, goal_state={"payment_status": "completed"}, ) # 3. Execute via your payment processor (your logic) payment = process_payment(verify.release_token) # 4. ATTEST — Record what actually happened attest = client.attest( agent_id="commerce-agent-003", action_description="Processed $500.00 subscription renewal", action_payload={ "amount": 500.00, "currency": "USD", "processor_ref": payment.reference_id, "status": payment.status, }, ) # 5. VERIFY OUTCOME — Did the result match the intent? outcome = client.verify_outcome( agent_id="commerce-agent-003", intent_id=bind.intent_id, binding_id=bind.binding_id, actual_state={"payment_status": payment.status}, ) print(f"Chain length: {attest.chain_length}") print(f"Outcome: {outcome.status}") # ACHIEVED

Compliance Evidence Bundle — For Auditors

# Generate audit-ready evidence for all agent payment decisions bundle = client.bundle( agent_id="commerce-agent-003", time_range_start="2026-01-01T00:00:00Z", time_range_end="2026-03-31T23:59:59Z", include_intent_chains=True, include_pqc_signatures=True, include_verification_instructions=True, ) print(f"Records: {bundle.record_count}") print(f"Chain integrity: {bundle.chain_integrity}") # Present bundle to compliance, risk, or audit teams

What Kevros does NOT do

Precision about scope and capabilities.

Kevros governs AI agent decisions upstream of the payment rail. It does not participate in, replace, or modify any part of the payment processing stack.

Process, store, or transmit cardholder data or payment credentials
Operate within the cardholder data environment (CDE)
Replace or modify payment network protocols (Visa, Mastercard, etc.)
Execute transactions or interact directly with payment rails
Perform sanctions screening, KYC/AML checks, or identity verification
Route, clear, or settle payments between parties
Act as a payment processor, gateway, acquirer, or money transmitter
Provide PCI DSS, SOC 2, ISO 27001, or any other compliance certification
Developer Note
Kevros operates entirely outside the cardholder data environment. It governs agent decisions before they reach your payment processor. Your payment processor, network, and settlement systems remain unchanged.

Product Scope

Kevros is an AI governance enforcement product. It verifies whether an AI agent is authorized to take a specific action within configured policy boundaries, and produces cryptographic evidence of that governance decision. Kevros does not process payments, transmit funds, store payment credentials, or operate within any cardholder data environment. Kevros is not a payment processor, payment gateway, money transmitter, or financial services provider.

Certification Posture

TaskHawk Systems, LLC is a Virginia limited liability company. TaskHawk Systems does not hold PCI DSS certification, SOC 2 attestation, ISO 27001 certification, or any other third-party compliance certification. Kevros provides technical governance controls that organizations may use as components within their own compliance and risk management programs. Using Kevros does not confer any compliance status on the deploying organization.

No Regulatory Claims

Nothing on this page constitutes legal, financial, or regulatory advice. References to payment network protocols (Visa TAP, Mastercard Verifiable Intent, Google AP2) describe the public technical specifications of those protocols for positioning context only. Kevros is not endorsed by, affiliated with, or certified by any payment network, card brand, or financial regulatory body. Organizations deploying Kevros in payment-adjacent environments should consult their own legal counsel and compliance teams regarding applicable regulatory requirements.
