The control plane for machine-controlled money. Define what AI agents can do, under what limits, and with whose authority.
Today's authorization systems weren't built for autonomous agents
Every AI platform builds its own authorization. No cross-platform control, no portability.
Rules are hardcoded or assumed. No way to define fine-grained policies programmatically.
When agents spend money, who's responsible? Platforms don't want to own the decision.
Define policies, enforce limits, audit everything. Works with any payment rail.
Works across Stripe, PayPal, crypto, and any payment method
Real-time authorization decisions without blocking payments
Immutable event stream for compliance and debugging
const { Lexiso } = require('lexiso');
const client = new Lexiso('sk_live_...');
const decision = await client.authorize(
'agent_abc123',
45.00,
{ merchant: 'shopify.com' }
);
if (decision.decision === 'allow') {
processPayment();
} else {
showDenial(decision.reason);
}npm install lexiso
Available for Python, Node.js, Go, and Ruby
Lexiso sits upstream of payments. We don't custody funds, process transactions, or compete with rails.
Defines policies: "Agent X can spend up to $100/day on books"
Evaluates request: "Does this purchase comply with policy?"
Requests authorization: "I want to buy a $45 programming book"
Executes transaction via Stripe, PayPal, crypto, or any method
