> ## 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.

# News-Use (News Monitor)

> Monitor news websites and extract articles with sentiment analysis using browser agents and Google Gemini.

<Note>
  This demo requires browser-use v0.7.7+.
</Note>

<video controls className="w-full aspect-video rounded-xl" src="https://browser-use.github.io/media/demos/news_use.mp4" />

## Features

1. Agent visits any news website automatically
2. Finds and clicks the most recent headline article
3. Extracts title, URL, posting time, and full content
4. Generates short/long summaries with sentiment analysis
5. Persistent deduplication across monitoring sessions

## Setup

Make sure the newest version of browser-use is installed:

```bash theme={null}
pip install -U browser-use
```

Export your Gemini API key, get it from: [Google AI Studio](https://makersuite.google.com/app/apikey)

```bash theme={null}
export GOOGLE_API_KEY='your-google-api-key-here'
```

Clone the repo, cd to the app

```bash theme={null}
git clone https://github.com/browser-use/browser-use.git
cd browser-use/examples/apps/news-use
```

## Usage Examples

```bash theme={null}
# One-time extraction - Get the latest article and exit
python news_monitor.py --once

# Monitor Bloomberg continuously (default)
python news_monitor.py

# Monitor TechCrunch every 60 seconds
python news_monitor.py --url https://techcrunch.com --interval 60

# Debug mode - See browser in action
python news_monitor.py --once --debug
```

## Output Format

Articles are displayed with timestamp, sentiment emoji, and summary:

```
[2025-09-11 02:49:21] - 🟢 - Klarna's IPO raises $1.4B, benefiting existing investors
[2025-09-11 02:54:15] - 🔴 - Tech layoffs continue as major firms cut workforce
[2025-09-11 02:59:33] - 🟡 - Federal Reserve maintains interest rates unchanged
```

**Sentiment Indicators:**

* 🟢 **Positive** - Good news, growth, success stories
* 🟡 **Neutral** - Factual reporting, announcements, updates
* 🔴 **Negative** - Challenges, losses, negative events

## Data Persistence

All extracted articles are saved to `news_data.json` with complete metadata:

```json theme={null}
{
  "hash": "a1b2c3d4...",
  "pulled_at": "2025-09-11T02:49:21Z",
  "data": {
    "title": "Klarna's IPO pops, raising $1.4B",
    "url": "https://techcrunch.com/2025/09/11/klarna-ipo/",
    "posting_time": "12:11 PM PDT · September 10, 2025",
    "short_summary": "Klarna's IPO raises $1.4B, benefiting existing investors like Sequoia.",
    "long_summary": "Fintech Klarna successfully IPO'd on the NYSE...",
    "sentiment": "positive"
  }
}
```

## Programmatic Usage

```python theme={null}
import asyncio
from news_monitor import extract_latest_article

async def main():
    # Extract latest article from any news site
    result = await extract_latest_article(
        site_url="https://techcrunch.com",
        debug=False
    )
    
    if result["status"] == "success":
        article = result["data"]
        print(f"📰 {article['title']}")
        print(f"😊 Sentiment: {article['sentiment']}")
        print(f"📝 Summary: {article['short_summary']}")

asyncio.run(main())
```

## Advanced Configuration

```python theme={null}
# Custom monitoring with filters
async def monitor_with_filters():
    while True:
        result = await extract_latest_article("https://bloomberg.com")
        if result["status"] == "success":
            article = result["data"]
            # Only alert on negative market news
            if article["sentiment"] == "negative" and "market" in article["title"].lower():
                send_alert(article)
        await asyncio.sleep(300)  # Check every 5 minutes
```
