# Requires Python 3.11+
pip install skyvern
```

```bash TypeScript
# Requires Node.js 18+
npm install @skyvern/client
```
</CodeGroup>

<CodeGroup>
```python Python
import asyncio
from skyvern import Skyvern

async def main():
    client = Skyvern(api_key="YOUR_API_KEY")
    result = await client.run_task(
        prompt="Get the title of the top post on Hacker News",
        url="https://news.ycombinator.com",
        wait_for_completion=True,
    )
    print(result.output)

asyncio.run(main())
```

```typescript TypeScript
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);
```
</CodeGroup>

**Constructor:**

<CodeGroup>
```python Python
Skyvern(
    api_key: str,                          # Required
    base_url: str | None = None,           # Override for self-hosted deployments
    environment: SkyvernEnvironment = CLOUD,# CLOUD, STAGING, or LOCAL
    timeout: float | None = None,          # HTTP request timeout (seconds)
)

# Local mode (Python only - runs entirely on your machine, reads .env)
client = Skyvern.local()
```

```typescript TypeScript
new Skyvern({
  apiKey: string,                              // Required
  baseUrl?: string,                            // Override for self-hosted deployments

## Browser Automation

### SkyvernBrowser

<CodeGroup>
```python Python
# Launch / connect
browser = await client.launch_cloud_browser(timeout=60, proxy_location=None)
browser = await client.use_cloud_browser(timeout=60, proxy_location=None)
browser = await client.connect_to_cloud_browser_session("pbs_abc123")
browser = await client.connect_to_browser_over_cdp("http://localhost:9222")
browser = await client.launch_local_browser(headless=False, port=9222)  # Python only

# Get pages
page = await browser.get_working_page()   # Most recent page, or creates one
page = await browser.new_page()            # Always creates a new tab
page = await browser.get_page_for(pw_page) # Wrap existing Playwright Page (Python only)
await browser.close()                      # Close browser and cloud session
```

```typescript TypeScript
// Launch / connect
const browser = await skyvern.launchCloudBrowser({ timeout: 60 });
const browser = await skyvern.useCloudBrowser({ timeout: 60 });
const browser = await skyvern.connectToCloudBrowserSession("pbs_abc123");
const browser = await skyvern.connectToBrowserOverCdp("http://localhost:9222");
// launch_local_browser - Python only, no TS equivalent

// Get pages
const page = await browser.getWorkingPage();   // Most recent page, or creates one
const page = await browser.newPage();           // Always creates a new tab
// get_page_for - Python only, no TS equivalent
await browser.close();                          // Close browser and cloud session
```
</CodeGroup>

### SkyvernPage

AI-enhanced Playwright methods - pass a selector for standard Playwright, add a prompt for AI fallback, or use prompt alone for pure AI.

<CodeGroup>
```python Python
# act - freeform AI action
await page.act("Click the login button")

# extract - structured data extraction
data = await page.extract("Extract all products", schema={...})

# validate - page state assertion, returns bool
ok = await page.validate("User is logged in")

# prompt - ask LLM about the page
result = await page.prompt("What is the heading?", schema={...})

# locator - AI element locator returning chainable AILocator (Python only)
locator = page.locator(prompt="the submit button")
await locator.click()

# click - selector, AI, or both with fallback
await page.click("#submit-btn")
await page.click(prompt="Click the submit button")
await page.click("#submit-btn", prompt="Click submit")

# fill - selector, AI, or both with fallback
await page.fill("#email", value="user@example.com")
await page.fill(prompt="Fill email with user@example.com")

# select_option - selector, AI, or both with fallback
await page.select_option("#country", value="us")
await page.select_option(prompt="Select United States")

# type - character-by-character input (Python only)
await page.type("#search", value="query")

# hover (Python only)
await page.hover("#menu-item", intention="Hover over the menu")

# scroll (Python only)
await page.scroll(0, 500)

# upload_file (Python only)
await page.upload_file("#file-input", files="/path/to/file.pdf")

# fill_form - AI full form fill (Python only)
await page.fill_form(data={"name": "John", "email": "john@example.com"})

# fill_multipage_form - across page transitions (Python only)
await page.fill_multipage_form(data={...}, max_pages=5)

# fill_from_mapping - explicit field→value mapping (Python only)
await page.fill_from_mapping(form_fields=fields, mapping={0: "John"}, data={...})

# extract_form_fields - get all fields with metadata (Python only)
fields = await page.extract_form_fields()

# validate_mapping - verify mapping works (Python only)
is_valid = await page.validate_mapping(form_fields=fields, mapping={...}, prompt="Validate fields")

# fill_autocomplete - typeahead handling (Python only)
await page.fill_autocomplete(selector="#city", value="San Francisco")

# frame_switch - switch iframe context (Python only)
await page.frame_switch(selector="#payment-iframe")
page.frame_main()                    # back to main frame
frames = await page.frame_list()     # list all frames
```

```typescript TypeScript
// act - freeform AI action
await page.act("Click the login button");

// extract - structured data extraction
const data = await page.extract({ prompt: "Extract all products", schema: {...} });

// validate - page state assertion, returns boolean
const ok = await page.validate("User is logged in");

// prompt - ask LLM about the page
const result = await page.prompt("What is the heading?", { heading: { type: "string" } });

// find / AILocator - Python only, no TS equivalent

// click - selector, AI, or both with fallback
await page.click("#submit-btn");
await page.click({ prompt: "Click the submit button" });
await page.click("#submit-btn", { prompt: "Click submit" });

// fill - selector, AI, or both with fallback
await page.fill("#email", "user@example.com");
await page.fill({ prompt: "Fill email with user@example.com" });

// selectOption - selector, AI, or both with fallback
await page.selectOption("#country", "us");
await page.selectOption({ prompt: "Select United States" });

// type, hover, scroll, upload_file - Python only
// fill_form, fill_multipage_form, fill_from_mapping - Python only
// extract_form_fields, validate_mapping, fill_autocomplete - Python only
// frame_switch, frame_main, frame_list - Python only
```
</CodeGroup>

### Page Agent

Full task/workflow execution in the context of the current page. Always waits for completion.

<CodeGroup>
```python Python
# run_task
result = await page.agent.run_task("Fill out the form", data_extraction_schema={...}, max_steps=10, timeout=1800)

# login - supports skyvern, bitwarden, onepassword, azure_vault
await page.agent.login(credential_type=CredentialType.skyvern, credential_id="cred_123")

# download_files
result = await page.agent.download_files("Download the invoice PDF", download_suffix=".pdf")

# run_workflow
result = await page.agent.run_workflow("wpid_abc123", parameters={"key": "value"})
```

```typescript TypeScript
// runTask
const result = await page.agent.runTask("Fill out the form", {
  dataExtractionSchema: {...}, maxSteps: 10, timeout: 1800,
});

// login - supports skyvern, bitwarden, 1password, azure_vault
await page.agent.login("skyvern", { credentialId: "cred_123" });

// downloadFiles
const result = await page.agent.downloadFiles("Download the invoice PDF", {
  downloadSuffix: ".pdf",
});

// runWorkflow
const result = await page.agent.runWorkflow("wpid_abc123", {
  parameters: { key: "value" },
});
```
</CodeGroup>

---

## Error Handling

<CodeGroup>
```python Python
from skyvern.client.core import ApiError
from skyvern.client.errors import NotFoundError

try:
    run = await client.get_run("tsk_nonexistent")
except NotFoundError as e:
    print(e.status_code, e.body)    # 404
except ApiError as e:
    print(e.status_code, e.body)    # Any other HTTP error
```

```typescript TypeScript
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 SkyvernError) {
    console.log(e.statusCode, e.body);    // Any other HTTP error
  }
}
```
</CodeGroup>

**Error types:** `BadRequestError` (400), `ForbiddenError` (403), `NotFoundError` (404), `ConflictError` (409), `UnprocessableEntityError` (422). All inherit from `ApiError` (Python) or `SkyvernError` (TypeScript).

Run failure is not an exception - check `result.status` (`completed`, `failed`, `terminated`, `timed_out`, `canceled`).

---

## Request options

Every method accepts `request_options` (Python) or a second options argument (TypeScript) for per-request overrides:

<CodeGroup>
```python Python
from skyvern.client.core import RequestOptions

request_options=RequestOptions(
    timeout_in_seconds=120,
    max_retries=3,
    additional_headers={"x-custom-header": "value"},
)
```

```typescript TypeScript
{
  timeoutInSeconds: 120,
  maxRetries: 3,
  headers: { "x-custom-header": "value" },
  abortSignal: controller.signal,  // TypeScript only
  apiKey: "override-key",          // TypeScript only
}
```
</CodeGroup>

---

## Key constraints

- `browser_profile_id` works with `run_workflow` only - silently ignored by `run_task`.
- Python `download_files` does not support `wait_for_completion` - poll manually or use webhooks.
- Only workflow runs with `persist_browser_session=True` produce archives for profile creation.
- `launch_local_browser` requires Python local mode (`Skyvern.local()`).
- `page.agent` methods always wait for completion.
- Python-only features: `launch_local_browser`, `get_page_for`, `locator`/`AILocator`, `type`, `hover`, `scroll`, `upload_file` (page-level), form automation (`fill_form`, `fill_multipage_form`, `fill_from_mapping`, `extract_form_fields`, `validate_mapping`, `fill_autocomplete`), iframe management (`frame_switch`, `frame_main`, `frame_list`).
