> ## 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.

# Secure Setup

## Secure Setup with Azure OpenAI

Enterprise-grade security with Azure OpenAI, data privacy protection, and restricted browser access.

```python theme={null}
import asyncio
import os
from dotenv import load_dotenv
load_dotenv()
os.environ['ANONYMIZED_TELEMETRY'] = 'false'
from browser_use import Agent, BrowserProfile, ChatAzureOpenAI

# Azure OpenAI configuration
api_key = os.getenv('AZURE_OPENAI_KEY')
azure_endpoint = os.getenv('AZURE_OPENAI_ENDPOINT')
llm = ChatAzureOpenAI(model='gpt-4.1-mini', api_key=api_key, azure_endpoint=azure_endpoint)

# Secure browser configuration
browser_profile = BrowserProfile(
    allowed_domains=['*google.com', 'browser-use.com'], 
    enable_default_extensions=False
)

# Sensitive data filtering
sensitive_data = {'company_name': 'browser-use'}

# Create secure agent
agent = Agent(
    task='Find the founders of the sensitive company_name',
    llm=llm,
    browser_profile=browser_profile,
    sensitive_data=sensitive_data
)

async def main():
    await agent.run(max_steps=10)

asyncio.run(main())
```

## Security Features

**Azure OpenAI:**

* NOT used to train OpenAI models
* NOT shared with other customers
* Hosted entirely within Azure
* 30-day retention (or zero with Limited Access Program)

**Browser Security:**

* `allowed_domains`: Restrict navigation to trusted sites
* `enable_default_extensions=False`: Disable potentially dangerous extensions
* `sensitive_data`: Filter sensitive information from LLM input
