Quickstarts

Choose the thing you are trying to ship. Each path starts small and gives you the pieces you need to take the next step.

Chat

Your first response

Use the Xpectrum SDK from your server, pass a stable user identifier, and send a message to your agent.

import { XpectrumChat } from "xpectrum";

const chat = new XpectrumChat({
  baseUrl: "https://cloud.xpectrum.dev/v1",
  apiKey: process.env.XPECTRUM_API_KEY!,
  user: "user-123",
});

const response = await chat.send("Hello from my app");
console.log(response.content);

Read the complete SDK Quickstart or explore chat completions, models, and threads.

Workflow

From trigger to outcome

Workflows coordinate tools, applications, approvals, and agents in one run. Start a run synchronously, or stream progress when the work takes longer.

curl https://cloud.xpectrum.dev/v1/runs \
  -H "Authorization: Bearer $XPECTRUM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"workflow_id":"your-workflow-id","input":{"customer_id":"cus_123"}}'

Read about runs and cancelling in-flight work.

Voice

Give the same application a voice

Build real-time voice calls with live transcription, microphone controls, and call lifecycle events. Your voice experience can use the same agent, tools, and knowledge as chat.

Explore the Voice Module and see how to handle the browser connection safely.

Interface

Add the interface when you need it

Use a drop-in chat window, voice orb, or combined widget when the product experience matters more than writing UI plumbing.

Add a widget or follow the JavaScript guide.
