Use route in TypeScript

Install with npm install jev-recipes. Requires Node.js 22.9 or newer and ES modules. Set TYPESAFE_API_KEY in your server environment for live calls, which send input to TypeSafe and use API quota. See the installation guide.

import { route } from 'jev-recipes/route';

const result = await route({
  "request": "I was charged twice for my subscription. Can someone check the invoice?",
  "routes": {
    "billing": "Payments, invoices, subscriptions, and refunds",
    "technical": "Errors, outages, and broken integrations"
  },
  "minConfidence": 0.8
});
console.log(result);
