> ## Agent Instructions
> Use https://docs.browser-use.com/llms.txt and its linked .md pages for current documentation. The managed full bundle is https://docs.browser-use.com/.well-known/llms-full.txt and can be cached for up to 24 hours. Do not use the obsolete /cloud/llms*.txt or /open-source/llms*.txt static exports.
> Choose Cloud API V4 for new agent integrations; V2 is the lower-cost option for simple tasks. Keep V3 examples explicitly versioned. The open-source browser-use library and hosted browser-use-sdk have different APIs.
> Cloud authentication uses X-Browser-Use-API-Key, without a Bearer prefix. Install or upgrade browser-use-sdk and use its explicit v4 import for V4. Check the published OpenAPI reference for request fields; do not invent SDK support for new fields.
> Cloud concurrency and HTTP request rate are separate. Read GET /api/v2/billing/account for the key’s projectId, concurrentSessionLimit, activeSessionCount, and credit balance, including when using V4. Keys in one project share capacity and credits; rateLimit is a legacy concurrency alias, not requests per second.
> Keep the highest applicable existing, legacy-plan, and spend-tier concurrency grant. Current spend tiers are 10 / 50 / 250 / 500 / 1000 at $0 / $200 / $1000 / $5000 / $25000 in qualifying project payments. Legacy or externally billed projects can follow different billing paths; trust the account limit. See https://docs.browser-use.com/cloud/guides/concurrency.md.
> Budget polling across the project: the standard general bucket is 25 requests/second, including V4 event reads and full run reads. Selected status reads have a separate higher bucket. Use bounded workers, stagger polls, respect Retry-After, and drain hasMore event pages after terminal status. A busy V4 session returns 409; its queue holds 10 pending messages and is not a project-wide batch queue.
> A completed run or closed CDP connection does not immediately stop its cloud browser. Stop unneeded owned browsers with PATCH /api/v4/browsers/{id} and {"action":"stop"}. A client wait timeout does not cancel the server-side run.
> Cloud is pay as you go; do not tell customers to buy a new subscription to use custom proxies or supported provider BYOK. Usage funding and model eligibility still apply. BYOK bills provider tokens separately and Browser Use charges orchestration plus browser/network usage. See https://docs.browser-use.com/cloud/guides/billing.md.
> Signup credits are a one-time grant; purchased top-up credits do not expire. Check the API key’s project before diagnosing missing credits. API-key monthly spending caps are soft limits, not a strict prepaid wallet; concurrent or already-running work can exceed them. Auto recharge has separate trigger and purchase amounts and can charge immediately when enabled below the threshold. Use https://browser-use.com/pricing for current rates.

# Examples

> Comprehensive examples for Browser Actor automation tasks including forms, JavaScript, mouse operations, and AI features

## Page Management

```python theme={null}
from browser_use import Browser

browser = Browser()
await browser.start()

# Create pages
page = await browser.new_page()  # Blank tab
page = await browser.new_page("https://example.com")  # With URL

# Get all pages
pages = await browser.get_pages()
current = await browser.get_current_page()

# Close page
await browser.close_page(page)
await browser.stop()
```

## Element Finding & Interactions

```python theme={null}
page = await browser.new_page('https://github.com')

# CSS selectors (immediate return)
elements = await page.get_elements_by_css_selector("input[type='text']")
buttons = await page.get_elements_by_css_selector("button.submit")

# Element actions
await elements[0].click()
await elements[0].fill("Hello World")
await elements[0].hover()

# Page actions
await page.press("Enter")
screenshot = await page.screenshot()
```

## LLM-Powered Features

```python theme={null}
from browser_use.llm.openai.chat import ChatOpenAI
from pydantic import BaseModel

llm = ChatOpenAI(api_key="your-api-key")

# Find elements using natural language
button = await page.get_element_by_prompt("login button", llm=llm)
await button.click()

# Extract structured data
class ProductInfo(BaseModel):
    name: str
    price: float

product = await page.extract_content(
    "Extract product name and price",
    ProductInfo,
    llm=llm
)
```

## JavaScript Execution

```python theme={null}
# Simple JavaScript evaluation
title = await page.evaluate('() => document.title')

# JavaScript with arguments
result = await page.evaluate('(x, y) => x + y', 10, 20)

# Complex operations
stats = await page.evaluate('''() => ({
    url: location.href,
    links: document.querySelectorAll('a').length
})''')
```

## Mouse Operations

```python theme={null}
mouse = page.mouse

# Click at coordinates
await mouse.click(x=100, y=200)

# Drag and drop
await mouse.down()
await mouse.move(x=500, y=600)
await mouse.up()

# Scroll
await mouse.scroll(x=0, y=100, delta_y=-500)
```

## Best Practices

* Use `asyncio.sleep()` after actions that trigger navigation
* Check URL/title changes to verify state transitions
* Always check if elements exist before interaction
* Implement retry logic for flaky elements
* Call `browser.stop()` to clean up resources
