Welcome to the Browser Use Cloud examples! This folder contains progressively complex examples to help you get started with the Browser Use Cloud API quickly and efficiently.

📋 Prerequisites

API Key: Get your API key from cloud.browser-use.com
Python Environment: Python 3.11+ with dependencies
Environment Variables: Configure your API settings

Quick Setup

# Create virtual environment and install dependencies (from project root)
uv venv --python 3.11
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv sync

# Set environment variables
export BROWSER_USE_API_KEY="your_api_key_here"
export BROWSER_USE_BASE_URL="https://api.browser-use.com/api/v1"  # Optional
export BROWSER_USE_TIMEOUT="30"  # Optional: request timeout in seconds

# Or use .env file (recommended)
cp examples/cloud/env.example .env
# Edit .env with your values

# Run examples from project root
python examples/cloud/01_basic_task.py

🎯 Examples Overview

🚀 Easy Cloud Setup Examples

01_basic_task.py - Your first cloud task (start here!)
02_fast_mode_gemini.py - ⚡ Ultra-fast mode with Gemini Flash & Fireship humor
03_structured_output.py - Get structured JSON responses
04_proxy_usage.py - 🌍 Proxy for geo-restrictions & captcha solving
05_search_api.py - 🔍 Search API for content extraction (BETA)

💰 Cost Optimization Tips

Use Gemini Flash for fastest/cheapest execution ($0.01/step)
Disable proxy when not needed for captcha solving
Disable element highlighting for better performance
Set max_agent_steps to prevent runaway costs
Use structured output to reduce parsing overhead
Add timeouts and retries for reliability in production
Use domain restrictions when working with secrets

🎨 Fast Mode Configuration

For maximum speed and cost efficiency:

{
    "llm_model": "gemini-2.5-flash",
    "use_proxy": False,
    "highlight_elements": False,
    "use_adblock": True,
    "max_agent_steps": 50
}

🔐 Security & Advanced Features

Using Proxy

{
    "use_proxy": True,
    "proxy_country_code": "us",  # 'us', 'fr', 'it', 'jp', 'au', 'de', 'fi', 'ca'
}

Passing Secrets Securely

{
    "secrets": {
        "username": "your_username",
        "password": "your_password",
        "api_key": "your_api_key"
    },
    "allowed_domains": ["*.yoursite.com"]  # Recommended with secrets
}

🔍 Search API (BETA)

The Search API extracts content by actually browsing websites (not cached results):

Simple Search (Multi-site)

# Cost: 1¢ × depth × websites
{
    "query": "latest AI news",
    "max_websites": 5,
    "depth": 2
}

URL Search (Single site)

# Cost: 1¢ × depth  
{
    "url": "https://example.com",
    "query": "pricing information",
    "depth": 3
}

🔧 Production Best Practices

Timeouts: All examples include 30-second timeouts with retry logic
Error Handling: Comprehensive error catching and status code validation
Security: Use environment variables, domain restrictions with secrets
Reliability: Built-in retries for network issues and rate limits
Automation: CLI arguments instead of interactive prompts for CI/CD
