> ## 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.

# Remote Browser

> Connect to remote browsers via CDP — use with the Cloud, Browserbase, or any remote Chrome instance.

### Browser-Use Cloud Browser or CDP URL

The easiest way to use a cloud browser is with the built-in Browser-Use cloud service:

```python theme={null}
from browser_use import Agent, Browser, ChatBrowserUse

# Simple: Use Browser-Use cloud browser service
browser = Browser(
    use_cloud=True,  # Automatically provisions a cloud browser
)

# Advanced: Configure cloud browser parameters
# Using this settings can bypass any captcha protection on any website
browser = Browser(
    cloud_profile_id='your-profile-id',  # Optional: specific browser profile
    cloud_proxy_country_code='us',  # Optional: proxy location (us, uk, fr, it, jp, au, de, fi, ca, in)
    cloud_timeout=30,  # Optional: session timeout in minutes (MAX free: 15min, paid: 240min)
)

# Or use a CDP URL from any cloud browser provider
browser = Browser(
    cdp_url="http://remote-server:9222"  # Get a CDP URL from any provider
)

agent = Agent(
    task="Your task here",
    llm=ChatBrowserUse(),
    browser=browser,
)
```

**Prerequisites:**

1. Get an API key from [cloud.browser-use.com](https://cloud.browser-use.com/new-api-key)
2. Set BROWSER\_USE\_API\_KEY environment variable

**Cloud Browser Parameters:**

* `cloud_profile_id`: UUID of a browser profile (optional, uses default if not specified)
* `cloud_proxy_country_code`: Country code for proxy location - supports: us, uk, fr, it, jp, au, de, fi, ca, in
* `cloud_timeout`: Session timeout in minutes (free users: max 15 min, paid users: max 240 min)

**Benefits:**

* ✅ No local browser setup required
* ✅ Scalable and fast cloud infrastructure
* ✅ Automatic provisioning and teardown
* ✅ Built-in authentication handling
* ✅ Optimized for browser automation
* ✅ Global proxy support for geo-restricted content

### Third-Party Cloud Browsers

You can pass in a CDP URL from any remote browser

### Proxy Connection

```python theme={null}

from browser_use import Agent, Browser, ChatBrowserUse
from browser_use.browser import ProxySettings

browser = Browser(
    headless=False,
    proxy=ProxySettings(
        server="http://proxy-server:8080",
        username="proxy-user",
        password="proxy-pass"
    ),
    cdp_url="http://remote-server:9222"
)


agent = Agent(
    task="Your task here",
    llm=ChatBrowserUse(),
    browser=browser,
)
```
