Complete Reference (For LLMs)

Complete TypeScript SDK reference covering every Skyvern client method, parameter, return type, and error class on a single page for quick lookup.

Install and initialize

npm install @skyvern/client

import { Skyvern } from "@skyvern/client";

const skyvern = new Skyvern({ apiKey: "YOUR_API_KEY" });

const result = await skyvern.runTask({
  body: {
    prompt: "Get the title of the top post on Hacker News",
    url: "https://news.ycombinator.com",
  },
  waitForCompletion: true,
});
console.log(result.output);

Constructor:

new Skyvern({
  apiKey: string,                              // Required
  baseUrl?: string,                            // Override for self-hosted deployments
  environment?: SkyvernEnvironment | string,   // Cloud (default), Staging, or Local
  timeoutInSeconds?: number,                   // HTTP request timeout (default: 60)
  maxRetries?: number,                         // Retry count (default: 2)
  headers?: Record<string, string>,            // Additional headers
})

Environments:

import { SkyvernEnvironment } from "@skyvern/client";
// SkyvernEnvironment.Cloud  → "https://api.skyvern.com"
// SkyvernEnvironment.Staging → "https://api-staging.skyvern.com"
// SkyvernEnvironment.Local  → "http://localhost:8000"

All methods return promises. Requires Node.js 18+.

Imports

import {
  Skyvern,                   // Main client class
  SkyvernEnvironment,        // Cloud, Staging, Local
  SkyvernError,              // Base error class
  SkyvernTimeoutError,       // HTTP timeout error
  SkyvernApi,                // Namespace for API types and error subclasses
} from "@skyvern/client";

// HTTP error subclasses via SkyvernApi namespace:
// SkyvernApi.BadRequestError          — 400
// SkyvernApi.ForbiddenError           — 403
// SkyvernApi.NotFoundError            — 404
// SkyvernApi.ConflictError            — 409
// SkyvernApi.UnprocessableEntityError — 422

Important: SkyvernError and SkyvernTimeoutError are top-level exports. The HTTP-specific errors (BadRequestError, etc.) extend SkyvernError and are accessed via the SkyvernApi namespace.

---

Browser automation (Playwright + AI)

The TypeScript SDK extends Playwright with AI capabilities via cloud browsers.

Launch browsers

// Launch new cloud browser
const browser = await skyvern.launchCloudBrowser({ timeout?: number, proxyLocation?: ProxyLocation });

// Reuse existing or create new
const browser = await skyvern.useCloudBrowser({ timeout?: number, proxyLocation?: ProxyLocation });

// Connect to existing cloud session
const browser = await skyvern.connectToCloudBrowserSession(browserSessionId: string);

// Connect via CDP
const browser = await skyvern.connectToBrowserOverCdp(cdpUrl: string);

Get pages

const page = await browser.getWorkingPage();  // Get or create page
const page = await browser.newPage();          // Always create new page
await browser.close();                         // Close browser and session

AI-enhanced page methods

// Click with AI fallback
await page.click("#selector");                                    // Standard Playwright
await page.click({ prompt: "Click the submit button" });          // AI-powered
await page.click("#selector", { prompt: "Click submit" });        // Selector + AI fallback

// Fill with AI fallback
await page.fill("#email", "[e-mail]");                    // Standard Playwright
await page.fill({ prompt: "Fill email with [e-mail]" });  // AI-powered
await page.fill("#email", "[e-mail]", { prompt: "..." }); // Selector + AI fallback

// Select with AI fallback
await page.selectOption("#country", "us");                                     // Standard Playwright
await page.selectOption({ prompt: "Select United States from country" });      // AI-powered

// Single AI actions
await page.act("Click the login button");                         // Perform an action
const data = await page.extract({ prompt: "Extract products" });  // Extract data
const ok = await page.validate("User is logged in");              // Validate state (boolean)
const resp = await page.prompt("What is the heading?", schema);   // LLM prompt

Full task execution via page.agent

await page.agent.runTask("Fill out the form", { timeout: 300 });
await page.agent.login("skyvern", { credentialId: "cred_123" });
await page.agent.downloadFiles("Download the PDF", { downloadSuffix: ".pdf" });
await page.agent.runWorkflow("wpid_abc", { parameters: { key: "value" } });

Error handling

import { SkyvernError, SkyvernTimeoutError, SkyvernApi } from "@skyvern/client";

try {
  const run = await skyvern.getRun("tsk_nonexistent");
} catch (e) {
  if (e instanceof SkyvernApi.NotFoundError) {
    console.log(e.statusCode, e.body);    // 404
  } else if (e instanceof SkyvernTimeoutError) {
    console.log("Request timed out");
  } else if (e instanceof SkyvernError) {
    console.log(e.statusCode, e.body);    // Any other HTTP error
  }
}

Error types: SkyvernApi.BadRequestError (400), SkyvernApi.ForbiddenError (403), SkyvernApi.NotFoundError (404), SkyvernApi.ConflictError (409), SkyvernApi.UnprocessableEntityError (422). All inherit from SkyvernError.

Completion timeout throws a standard Error:

try {
  const result = await skyvern.runTask({
    body: { prompt: "...", url: "..." },
    waitForCompletion: true,
    timeout: 300,
  });
} catch (e) {
  if (e instanceof Error && e.message.includes("Timeout")) {
    console.log("Task didn't complete in time");
  }
}

Run failure is not an exception — check result.status:

if (result.status === "failed") console.log(result.failure_reason);
if (result.status === "completed") console.log(result.output);

---

Request options

Override timeout, retries, or headers per-request (second parameter on all methods):

const result = await skyvern.runTask(
  { body: { prompt: "...", url: "..." } },
  {
    timeoutInSeconds: 120,
    maxRetries: 3,
    headers: { "x-custom-header": "value" },
    abortSignal: controller.signal,
  },
);

---

Polling pattern

When not using waitForCompletion:

const task = await skyvern.runTask({ body: { prompt: "...", url: "..." } });

const terminal = ["completed", "failed", "terminated", "timed_out", "canceled"];
let run;
while (true) {
  run = await skyvern.getRun(task.run_id);
  if (terminal.includes(run.status)) break;
  await new Promise((resolve) => setTimeout(resolve, 5000));
}
console.log(run.output);

---

Key constraints

• browser_profile_id works with runWorkflow only — silently ignored by runTask.
• Only workflow runs with persist_browser_session: true produce archives for profile creation.
• Session archiving is async — profile creation may need a short retry delay after a run completes.
• engine accepts string values: "skyvern_v1", "skyvern_v2", "openai_cua", "anthropic_cua", "ui_tars".
• Cloud browser methods (launchCloudBrowser, useCloudBrowser, connectToCloudBrowserSession) only work with Cloud or Staging environments.
• The SDK depends on playwright for browser automation features.
