🏗️ Architecture

Tiered Search Strategy (Free → Paid)

1. CACHE (0ms, $0.00) ← First check
   ↓
2. OpenClaw Tools (800ms, $0.00) ← Built-in oxylabs_web_search
   ↓
3. Free APIs (1.2s, $0.00) ← DuckDuckGo, Brave Search
   ↓
4. Google API (1.5s, $0.00*) ← 100 free/day
   ↓
5. Lightweight HTTP (2s, $0.001) ← Last resort

*First 100 queries/day free with Google API

🔧 Quick Start

# Install skill
clawhub install google-search-unlimited-v2
Install dependencies
pip install requests beautifulsoup4 lxml
Basic search
python3 search.py "your query"
With caching (recommended)
python3 search.py --cache "your query"

pip install lxml

🎯 Usage

# Basic search
python3 search.py "your query"
With caching
python3 search.py --cache "your query"
Force specific method
python3 search.py --method oxylabs "your query"

🔧 Configuration

Create .env file:

# Google API (optional)
GOOGLE_API_KEY=your_key
GOOGLE_CSE_ID=your_cx
Cache settings
CACHE_TTL_HOURS=24
MAX_CACHE_SIZE_MB=100
Rate limiting
MAX_REQUESTS_PER_MINUTE=10

📈 Performance Features

Query deduplication: Same query = cached result

Result compression: Store only essential data

Batch processing: Multiple queries in single API call

Smart retry: Exponential backoff on failures

Result validation: Filter out low-quality results

💰 Cost Optimization

Free Methods First

1. OpenClaw tools (no cost) 2. Free APIs (DuckDuckGo, Brave) 3. Google API (100 free/day)

Cache Strategy

Hot queries: Keep in memory

Warm queries: SQLite cache

Cold queries: Fresh fetch

Bandwidth Saving

Compress responses

Store only text (no HTML)

Pagination support

🛡️ Reliability

Multiple fallbacks: 4+ search methods

Automatic failover: If one fails, try next

Health checks: Monitor API status

Graceful degradation: Maintain service during outages

📊 Monitoring

Built-in metrics:

Success rate per method

Average response time

Cache hit ratio

Cost per query (estimated)

Example Output

{
  "query": "OpenClaw documentation",
  "method": "oxylabs",
  "cost_estimate": 0.0,
  "cache_hit": false,
  "response_time_ms": 850,
  "results": [
