Govern the Agent.
Never Touch the Funds.

The settlement layer is solved. The governance layer is empty. LimitLayer is the deterministic firewall between your AI agents' technical execution and your company's financial exposure — policy, budget, and vendor control across every processor and wallet you use.

Approved. Blocked. Escalated. Always one of three. Always auditable.

Agents optimize for execution, not compliance.

When a payment fails, an agent treats it like a technical puzzle. LimitLayer stops agents from hallucinating corporate finance policy in real-time.

Pre-Transaction

Unbounded Spend

Agents will blindly pay invoices. We intercept requests, enforce budget caps, and verify vendor whitelists before execution.

Post-Transaction

Hallucinating Policy

When errors happen, agents retry endlessly or switch to unapproved wallets. We catch the errors and dictate the business-approved next step.

The Core Issue: Existing payment systems were built for humans making deliberate purchases, not for autonomous agents making hundreds of micro-decisions per day.

How It Works

Three deterministic steps between intent and execution

1

Agent Requests Payment

The agent hits an HTTP 402 or requests a virtual card to complete a transaction.

2

LimitLayer Intercepts

We authenticate the mandate, check velocity, and verify the vendor against your corporate policy as code.

3

Execution or Escalation

The payment routes to Skyfire/Stripe, or it securely escalates to a human for review.

Our Solution

LimitLayer: The Governance Layer for AI Agent Payments

A governance layer that sits between AI agents and payment processors, evaluating policies and advising decisions before money leaves your account.

Intercept

Every transaction request is evaluated before reaching your payment processor

Decide

Your custom policies, budgets, and approval workflows evaluated in real-time

Monitor

Complete audit trail and real-time alerts for every decision

We don't replace Stripe—we add the governance layer Stripe doesn't provide. Keep your existing payment setup; we just add control on top.

Intelligence Layer

Beyond Guardrails: Payment Intelligence

LimitLayer doesn't just block bad transactions—it makes your agents smarter about payments with normalised decline data, intelligent retry logic, and fleet-wide risk visibility.

Decline Normalisation

Every wallet provider returns different error codes. LimitLayer translates them into a unified format your agents can understand.

Stripe: "card_declined"
LimitLayer: insufficient_balance (soft_decline)
Action: Retry with different method
PayPal: "INSTRUMENT_DECLINED"
LimitLayer: auth_failure (hard_decline)
Action: Escalate to human
  • Soft vs hard decline classification
  • Risk scoring per decline
  • Recommended next action
  • Provider-breakdown analytics

Smart Retry Advisory

Intelligent retry recommendations powered by real outcome data. Advises agents on whether to retry, how long to wait, and which provider to use.

// Advisory response
should_retry: true
delay: 30s
max_attempts: 3
alt_wallet: "wallet_backup_01"
penalty_risk: low
  • Never executes—pure advisory
  • Learns from outcome history
  • Provider-specific recovery rates
  • Penalty risk assessment

Portfolio Risk Monitor

Fleet-level health dashboard inspired by Visa's VAMP program. Spot problems before they become costly—across your entire agent fleet.

Fleet Health Score87/100
Approval Rate94.2%
Decline Rate5.1%
Dispute Rate0.3%
Retry Success67%
  • Per-agent risk profiles & anomaly scores
  • Merchant risk analysis
  • Severity-based alerts
  • 30-day health trend tracking

All intelligence is advisory—LimitLayer never touches funds. Your agents get smarter decisions while you maintain full control. All metrics are computed from transaction and outcome data.
