JavaScript SDK

JavaScript and TypeScript SDK for TypeSafe AI.

Quickstart

Install the SDK (Node.js 20 or newer):

npm install @typesafe-ai/sdk

Set TYPESAFE_API_KEY in your environment, then create and use the client:

import { choice, TypeSafeClient } from "@typesafe-ai/sdk";

const client = new TypeSafeClient();
const response = await client.systemOne({
  state: { document: "I was charged twice. Please fix this ASAP." },
  questions: {
    category: choice("What is this ticket about?", {
      billing: null,
      technical: null,
      other: null,
    }),
  },
});

console.log(response.answers.category.choice);

Answer types are inferred from your questions. The package includes ESM, CommonJS, and TypeScript declarations.
