Quickstart

import { HelixClient } from "@helixread/sdk";

const hx = new HelixClient({
  apiKey: process.env.HELIX_API_KEY!,
  baseUrl: "https://helixread.com",
});

const ctx = await hx.getContext({ symbols: ["NVDA"], depth: "deep", citations: true });
const session = await hx.createSession(["NVDA", "AMD"]);
const guard = await hx.guardValidate("NVDA RSI is 42", { sessionId: session.session_id as string });

Set HELIX_API_KEY once in .env — the client sends X-API-Key on every request automatically.
