Quickstart
Hello, AIR OS
import { AIREx } from "@airex/sdk";

const airex = new AIREx({
  apiKey: process.env.AIREX_API_KEY,
  env: "sandbox",
});

// REST: fetch a twin + AIRScore
const twin = await airex.properties.get("PRP-00A21");
const score = await airex.airscore.latest(twin.id);

// Event Bus: react to permits
await airex.events.subscribe("PermitFiled", async (evt) => {
  await airex.agents.invoke("permit-brief", {
    propertyId: evt.propertyId, hitl: true,
  });
});
