Use citation-match 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 { citationMatch } from 'jev-recipes/citation-match';

const result = await citationMatch({
  "claim": "Reset links expire after 30 minutes.",
  "passages": [
    {
      "id": "reset",
      "text": "Password reset links expire after 30 minutes."
    },
    {
      "id": "billing",
      "text": "Invoices are available on the Billing page."
    }
  ]
});
console.log(result);
