Quick Start

const { Lexiso } = require('lexiso');

const client = new Lexiso('sk_live_your_api_key');

// Authorize a purchase
const result = await client.authorize('agent_xxx', 25.00, {
  merchant: 'Amazon',
  category: 'shopping'
});

console.log(result.decision); // 'allow' or 'deny'
console.log(result.signature); // Cryptographic proof

AP2 Mandate Flow

// 1. User creates intent
const intent = await client.createIntent('agent_xxx', 'Buy coffee under $10', {
  max_amount: 10.00,
  categories: ['food', 'beverage']
});

// 2. Agent proposes cart
const cart = await client.createCart('agent_xxx', intent.id, [
  { name: 'Latte', price: 5.50, quantity: 1 }
], 'Starbucks');

console.log(cart.decision); // 'allow' or 'deny'
