```

## 🔧 Quick Start

### Basic Usage with Google Gemini

```python
from codex_weather_agent import create_weather_agent

# Create agent with Google Gemini (ALL PARAMETERS REQUIRED)
agent = create_weather_agent(
    llm_provider="google",                    # REQUIRED: Choose your LLM provider
    llm_model="gemini-2.5-flash",            # REQUIRED: Specify model name
    llm_api_key="your-google-api-key",       # REQUIRED: Your LLM API key
    openweather_api_key="your-openweather-key"  # REQUIRED: OpenWeather API key
)

# Have a natural conversation about weather
response = agent.chat("What's the weather like right now?")
print(response)

response = agent.chat("How about tomorrow in Tokyo?")
print(response)
```

### Using Different LLM Providers

```python
# OpenAI GPT-4 (ALL PARAMETERS REQUIRED)
agent = create_weather_agent(
    llm_provider="openai",
    llm_model="gpt-4",
    llm_api_key="your-openai-key",           # REQUIRED
    openweather_api_key="your-weather-key"   # REQUIRED
)

# Anthropic Claude (ALL PARAMETERS REQUIRED)
agent = create_weather_agent(
    llm_provider="anthropic", 
    llm_model="claude-3-sonnet",
    llm_api_key="your-anthropic-key",        # REQUIRED
    openweather_api_key="your-weather-key"   # REQUIRED
)

# Custom LLM
from langchain_openai import ChatOpenAI
custom_llm = ChatOpenAI(model="gpt-3.5-turbo", temperature=0.2)

agent = create_weather_agent(
    llm_provider="custom",
    llm_model="custom",  # Can be any string for custom LLM
    llm_api_key="not-used-for-custom",       # Still required
    openweather_api_key="your-weather-key",  # REQUIRED
    custom_llm=custom_llm
)
```

### Advanced Configuration

```python
from codex_weather_agent import WeatherAgent, LLMConfig, WeatherConfig

# Detailed configuration
llm_config = LLMConfig(
    provider="google",
    model="gemini-2.5-flash",
    temperature=0.1,
    max_tokens=1000,
    api_key="your-api-key"
)

weather_config = WeatherConfig(
    openweather_api_key="your-weather-key",
    request_timeout=10,
    default_units="metric"
)

# Create agent with custom configurations
agent = WeatherAgent(
    llm_config=llm_config,
    weather_config=weather_config,
    max_memory_conversations=10  # Remember last 10 conversations
)
```

### Streaming Responses

```python
# Get real-time streaming responses
for chunk in agent.stream_chat("Tell me about the weather in Paris"):
    print(chunk, end="", flush=True)
```

### Memory Management

```python
# Check memory usage
memory_info = agent.get_memory_info()
print(f"Conversations in memory: {memory_info['current_conversations']}")
print(f"LLM Provider: {memory_info['llm_provider']}")

# Clear conversation memory
agent.clear_memory()
```

## 🔑 API Keys (REQUIRED)

### ⚠️ **All API Keys Are Now Mandatory**

Starting from version 1.0.4, **ALL API keys are required** for the weather agent to function. This ensures reliable operation and prevents rate limiting issues.

### Required API Keys

1. **LLM Provider API Key** (mandatory - choose one):
   - **Google**: Get from [Google AI Studio](https://makersuite.google.com/app/apikey)
   - **OpenAI**: Get from [OpenAI Platform](https://platform.openai.com/api-keys)
   - **Anthropic**: Get from [Anthropic Console](https://console.anthropic.com/)

2. **OpenWeather API Key** (mandatory):
   - Get from [OpenWeatherMap](https://openweathermap.org/api)
   - Free tier available with 1,000 calls/day
   - **No longer optional** - you must provide your own key

### Setting API Keys

#### Environment Variables (Recommended)
```bash
export GOOGLE_API_KEY="your-google-api-key"
export OPENWEATHER_API_KEY="your-openweather-key"
```

#### Direct Parameter Passing
```python
agent = create_weather_agent(
    llm_api_key="your-llm-api-key",
    openweather_api_key="your-weather-key"
)
```

## 🌟 Example Conversations

The agent responds naturally without structured formatting:

```python
agent = create_weather_agent(
    llm_provider="google", 
    llm_model="gemini-2.5-flash",
    llm_api_key="your-key",
    openweather_api_key="your-weather-key"
)

# Natural weather queries
print(agent.chat("Hey, what's it like outside?"))
# "Hey there! Let me check your current location... It looks like you're in New York, and it's a beautiful sunny day with 72°F and clear skies!"

print(agent.chat("Should I bring an umbrella tomorrow?"))  
# "Based on tomorrow's forecast for New York, you should definitely grab an umbrella! There's rain expected in the afternoon with about 80% chance of precipitation..."

print(agent.chat("What about the air quality?"))
# "The air quality in your area is pretty good today with an AQI of 45, which means it's safe for outdoor activities and everyone can enjoy being outside!"
```

## 🛠️ Available Tools

The agent has access to these weather tools:

- `current_location()` - Detect user's location via IP
- `get_current_weather(city)` - Current weather conditions
- `get_weather_forecast(city)` - 5-day weather forecast
- `get_air_pollution(lat, lon)` - Air quality data
- `get_location_coordinates(location)` - Geocoding service

from codex_weather_agent import LLMConfig

config = LLMConfig(
    provider="google",  # "google", "openai", "anthropic", "custom"
    model="gemini-2.5-flash",
    api_key="your-key",
    temperature=0.1,    # Response randomness (0.0-1.0)
    max_tokens=1000,    # Maximum response length
    top_p=0.8,         # Nucleus sampling (Google only)
    top_k=40,          # Top-k sampling (Google only)
    additional_params={}  # Provider-specific parameters
)
```

    max_retries=3,              # Number of retry attempts
    enable_location_detection=True,  # Auto-detect user location
    default_units="metric"       # "metric", "imperial", "kelvin"
)
```

## 🧪 Error Handling

The package includes comprehensive error handling:

```python
from codex_weather_agent import WeatherAgentError, LLMConfigError, APIKeyError

try:
    agent = create_weather_agent(llm_provider="invalid")
except LLMConfigError as e:
    print(f"LLM configuration error: {e}")

try:
    response = agent.chat("What's the weather?")
except WeatherAgentError as e:
    print(f"Weather agent error: {e}")
```
