The OpenAI Agents SDK is OpenAI's official toolkit for building agents with typed tools, handoffs, guardrails, and tracing. The Steel integration runs each tool against a Steel cloud session, so you can stand up a typed browser agent that opens a session, navigates, extracts data, and returns a validated final report.

Available in TypeScript and Python.

Requirements

• Steel API Key: Active Steel subscription
• OpenAI API Key: A model supported by the Agents SDK
• Runtime: Node.js 20+ or Python 3.10+

Connect Steel to the OpenAI Agents SDK

Open a Steel session inside a typed Agents SDK tool():

import { tool } from "@openai/agents";
import { chromium } from "playwright";
import Steel from "steel-sdk";
import { z } from "zod";

const steel = new Steel({ steelAPIKey: STEEL_API_KEY });

const openSession = tool({
  name: "open_session",
  description: "Open a Steel cloud browser session.",
  parameters: z.object({}),
  execute: async () => {
    const session = await steel.sessions.create({});
    const browser = await chromium.connectOverCDP(
      `${session.websocketUrl}&apiKey=${STEEL_API_KEY}`,
    );
    return { sessionId: session.id, liveViewUrl: session.sessionViewerUrl };
  },
});
