## 📚 Usage Guide

### Basic Usage - Provider and Model Required

```python
from ScraperSage import scrape_and_summarize

# ✅ CORRECT: Specify both provider and model
scraper = scrape_and_summarize(provider="gemini", model="gemini-1.5-flash")
result = scraper.run({"query": "AI trends 2024"})

# ✅ CORRECT: Using OpenAI
scraper = scrape_and_summarize(provider="openai", model="gpt-4o-mini")
result = scraper.run({"query": "AI trends 2024"})

# ❌ INCORRECT: This will raise an error
# scraper = scrape_and_summarize()  # Missing provider and model
# scraper = scrape_and_summarize(provider="openai")  # Missing model
```

### Get Available Models

```python
from ScraperSage import get_available_models, get_supported_providers

# See all supported providers
providers = get_supported_providers()
print(f"Providers: {providers}")

# Get example models for each provider
for provider in providers:
    models = get_available_models(provider)
    print(f"\n{provider.upper()} example models:")
    for model_id, description in models.items():
        print(f"  - {model_id}: {description}")
```

### Advanced Configuration

```python
# All parameters with explicit model
params = {
    "query": "machine learning in healthcare",
    "max_results": 8,
    "max_urls": 12,
    "save_to_file": True
}

# Try different providers/models
providers_to_try = [
    {"provider": "gemini", "model": "gemini-1.5-pro"},

]

for config in providers_to_try:
    try:
        scraper = scrape_and_summarize(**config)
        result = scraper.run(params)
        if result["status"] == "success":
            print(f"✅ {config['provider']} with {config['model']} worked!")
            break
    except Exception as e:
        print(f"❌ {config['provider']}/{config['model']} failed: {e}")
        continue
```

## 🚨 Error Handling

### Common Errors and Solutions

```python
from ScraperSage import scrape_and_summarize, get_available_models

# ❌ Missing provider
try:
    scraper = scrape_and_summarize(model="gpt-4o")
except ValueError as e:
    print(f"Error: {e}")
    # Shows: Provider is required. Please specify one of: ['gemini', 'openai', 'openrouter', 'deepseek']

# ❌ Missing model
try:
    scraper = scrape_and_summarize(provider="openai")
except ValueError as e:
    print(f"Error: {e}")
    # Shows: Model is required for openai. Example models: ['gpt-4o-mini', 'gpt-4o', 'gpt-4-turbo']

# ✅ Get help with model selection
models = get_available_models("openai")
print(f"Available OpenAI models: {list(models.keys())}")

# ✅ Correct usage
scraper = scrape_and_summarize(provider="openai", model="gpt-4o-mini")
```

### Safe Model Selection Helper

```python
def safe_create_scraper(provider, model_preferences):
    """Try models in order of preference."""
    for model in model_preferences:
        try:
            scraper = scrape_and_summarize(provider=provider, model=model)
            print(f"✅ Successfully initialized {provider} with {model}")
            return scraper
        except Exception as e:
            print(f"❌ {provider}/{model} failed: {e}")
            continue
    
    raise ValueError(f"No working models found for {provider}")

# Usage
openai_preferences = ["gpt-4o", "gpt-4o-mini", "gpt-3.5-turbo"]
scraper = safe_create_scraper("openai", openai_preferences)
```

## 💡 Model Selection Strategy

### Recommended Approach

```python
from ScraperSage import scrape_and_summarize, get_available_models

def create_scraper_with_fallback(provider_preferences):
    """Create scraper with provider/model fallbacks."""
    
    for provider_config in provider_preferences:
        provider = provider_config["provider"]
        models = provider_config["models"]
        
        print(f"🔍 Trying {provider}...")
        for model in models:
            try:
                scraper = scrape_and_summarize(provider=provider, model=model)
                print(f"✅ Success: {provider}/{model}")
                return scraper
            except Exception as e:
                print(f"❌ Failed: {provider}/{model} - {str(e)[:50]}...")
                continue
    
    raise ValueError("No working provider/model combinations found")

# Define your preferences
preferences = [
    {
        "provider": "openai",
        "models": ["gpt-4o", "gpt-4o-mini", "gpt-3.5-turbo"]
    },
    {
        "provider": "gemini", 
        "models": ["gemini-1.5-pro", "gemini-1.5-flash"]
    },
    {
        "provider": "openrouter",
        "models": ["anthropic/claude-3.5-sonnet", "openai/gpt-4o-mini"]
    }
]

scraper = create_scraper_with_fallback(preferences)
result = scraper.run({"query": "your search query"})
```

## 📊 Benefits of Explicit Model Selection

### ✅ Advantages
- **No surprises**: You always know which model is being used
- **Cost control**: Explicitly choose cost-effective models
- **Performance predictability**: Know exactly what capabilities you're getting
- **Future-proof**: New models don't change existing behavior
- **Debugging**: Easier to identify model-specific issues
- **Transparency**: Clear model usage in logs and results

### 📈 Best Practices
1. **Always specify both provider and model**
2. **Use get_available_models() to see examples**
3. **Implement fallback strategies for reliability**
4. **Test models with small queries first**
5. **Monitor costs when using premium models**
6. **Keep model preferences in configuration files**
