- **Comprehensive Error Handling** - Detailed exceptions for different error scenarios
- **Flexible Configuration** - Environment variable support with sensible defaults

## Installation

```bash
pip install pymercury
```

### Development Installation

For development or to run the examples:

```bash
# Clone the repository
git clone <repository-url>
cd pymercury

# Install dependencies
pip install -r requirements.txt

# Install in development mode
pip install -e .
```

## Quick Start

### Environment Setup (Recommended)

For security, use environment variables instead of hardcoding credentials:

1. **Create a `.env` file** in the project root:

   ```bash
   cp env.template .env
   ```

2. **Edit `.env` with your Mercury Energy credentials**:

   ```bash
   # Mercury Energy Credentials
   MERCURY_EMAIL=your-email@example.com
   MERCURY_PASSWORD=your-actual-password
   ```

3. **The library automatically loads these credentials**:
   ```python
   # No need to hardcode credentials!
   from pymercury import authenticate
   tokens = authenticate()  # Uses MERCURY_EMAIL and MERCURY_PASSWORD from .env
   ```

> **Security Note**: Never commit `.env` files to version control. The `.env` file is automatically ignored by git.

### Simple Authentication

```python
from pymercury import authenticate

# Get OAuth tokens
tokens = authenticate("your-email@example.com", "your-password")
print(f"Customer ID: {tokens.customer_id}")
print(f"Access Token: {tokens.access_token}")
```

### Complete Account Data

```python
from pymercury import get_complete_data

# Get everything in one call
data = get_complete_data("your-email@example.com", "your-password")

print(f"Customer ID: {data.customer_id}")
print(f"Account IDs: {data.account_ids}")
print(f"Electricity Services: {data.service_ids.electricity}")
print(f"Gas Services: {data.service_ids.gas}")
print(f"Broadband Services: {data.service_ids.broadband}")
```

### Main Client (Recommended)

```python
from pymercury import MercuryClient

# Create client and login
client = MercuryClient("your-email@example.com", "your-password")
client.login()

# Easy access to information
customer_id = client.customer_id
account_ids = client.account_ids
service_ids = client.service_ids

# Get complete data
complete_data = client.get_complete_account_data()
```

## Advanced Usage

### Separate OAuth and API Clients

```python
from pymercury.oauth import MercuryOAuthClient
from pymercury.api import MercuryAPIClient

# OAuth authentication only
oauth_client = MercuryOAuthClient("your-email@example.com", "your-password")
tokens = oauth_client.authenticate()

# API calls with existing tokens
api_client = MercuryAPIClient(tokens.access_token)
customer_info = api_client.get_customer_info(tokens.customer_id)
accounts = api_client.get_accounts(tokens.customer_id)
```

## Electricity Services

### Electricity Usage and Billing

```python
from pymercury.api import MercuryAPIClient

# Initialize API client with access token
api_client = MercuryAPIClient(access_token)

# Get electricity meter information
meter_info = api_client.get_electricity_meter_info(customer_id, account_id)
if meter_info:
    print(f"Meter Number: {meter_info.meter_number}")
    print(f"Meter Type: {meter_info.meter_type}")

# Get bill summary
bill_summary = api_client.get_bill_summary(customer_id, account_id)
if bill_summary:
    print(f"Current Balance: ${bill_summary.current_balance}")
    print(f"Due Date: {bill_summary.due_date}")
```

### Electricity Usage Data

```python
from pymercury.api import MercuryAPIClient

# Initialize API client with access token
api_client = MercuryAPIClient(access_token)

# Get electricity usage (defaults to last 14 days)
electricity_usage = api_client.get_electricity_usage(customer_id, account_id, service_id)
if electricity_usage:
    print(f"Total Usage: {electricity_usage.total_usage} kWh")
    print(f"Average Daily Usage: {electricity_usage.average_daily_usage} kWh")
    print(f"Average Temperature: {electricity_usage.average_temperature}°C")

# Get hourly electricity usage (2 days ending yesterday)
hourly_electricity = api_client.get_electricity_usage_hourly(customer_id, account_id, service_id)
if hourly_electricity:
    print(f"Hourly Usage Period: {hourly_electricity.start_date} to {hourly_electricity.end_date}")
    print(f"Total Hourly Usage: {hourly_electricity.total_usage} kWh")

# Get monthly electricity usage (1 year period)

- ✅ Each developer should have their own `.env` file
- ✅ Use environment variables in production deployments
- ✅ Regularly rotate your Mercury Energy password

#### Testing Environment Setup

You can verify your environment setup:

```bash
# Test credential loading
python3 -c "from mercury_examples import MERCURY_EMAIL; print('Email loaded:', MERCURY_EMAIL)"

# Run examples with your credentials
python3 mercury_examples.py
```

```python
from pymercury import MercuryConfig, MercuryClient

config = MercuryConfig(
    client_id="your-client-id",
    api_subscription_key="your-api-key",
    timeout=30
)

client = MercuryClient("your-email@example.com", "your-password", config=config)
```

## Error Handling

```python
from pymercury import (
    MercuryClient,
    MercuryAuthenticationError,
    MercuryAPIError,
    MercuryError
)

try:
    client = MercuryClient("your-email@example.com", "your-password")
