## 📦 Installation

```bash
pip install xfinance-python-sdk
```

## 🚀 Quick Start

```python
from xfinance_sdk import XFinanceClient
from xfinance_sdk.models.request import CompoundInterestRequest
from decimal import Decimal

# Initialize client
client = XFinanceClient(api_key="your-api-key")

# Calculate compound interest
request = CompoundInterestRequest(
    principal=Decimal("10000"),
    annual_rate=Decimal("0.05"),
    years=10,
    compounding_frequency=12
)

response = client.calculate_compound_interest(request)
print(f"Final amount: ${response.final_amount:,.2f}")
print(f"Total interest: ${response.total_interest:,.2f}")
```

## 📚 API Examples

### Compound Interest Calculation

```python
from xfinance_sdk import XFinanceClient
from xfinance_sdk.models.request import CompoundInterestRequest
from decimal import Decimal

client = XFinanceClient(api_key="your-api-key")

request = CompoundInterestRequest(
    principal=Decimal("10000"),
    annual_rate=Decimal("0.05"),
    years=10,
    compounding_frequency=12
)

response = client.calculate_compound_interest(request)
```

### Loan Payment Calculation

```python
from xfinance_sdk.models.request import LoanCalculationRequest

request = LoanCalculationRequest(
    loan_amount=Decimal("200000"),
    annual_rate=Decimal("0.035"),
    term_years=30
)

response = client.calculate_loan_payment(request)
```

### Investment Returns Calculation

```python
from xfinance_sdk.models.request import InvestmentReturnsRequest

request = InvestmentReturnsRequest(
    initial_investment=Decimal("5000"),
    monthly_contribution=Decimal("500"),
    expected_annual_return=Decimal("0.07"),
    years=20
)

response = client.calculate_investment_returns(request)
```

### Async Usage

```python
import asyncio
from xfinance_sdk import AsyncXFinanceClient

async def main():
    client = AsyncXFinanceClient(api_key="your-api-key")
    response = await client.calculate_compound_interest(request)
    await client.close()

asyncio.run(main())
```

## 🔐 Authentication

### API Key Authentication

```python
client = XFinanceClient(
    api_key="your-api-key",
    api_secret="your-api-secret"  # Optional
)
```

### User Authentication

```python
from xfinance_sdk.models.request import LoginRequest

# Login to get JWT token
login_request = LoginRequest(
    email="user@example.com",
    password="your-password"
)

login_response = client.login(login_request)

# Use token for authenticated requests
authenticated_client = XFinanceClient(api_key=login_response.token)
```

## ⚠️ Error Handling

```python
from xfinance_sdk.exceptions import (
    BadRequestError, UnauthorizedError, RateLimitError, ValidationError
)

try:
    response = client.calculate_compound_interest(request)
except UnauthorizedError as e:
    print(f"Authentication failed: {e.message}")
except BadRequestError as e:
    print(f"Invalid request: {e.message}")
except ValidationError as e:
    print(f"Validation errors: {e.errors}")
except RateLimitError as e:
    print(f"Rate limit exceeded: {e.message}")
```

## ⚙️ Configuration

### Environment Variables

```bash
export XFINANCE_API_KEY="your-api-key"
export XFINANCE_API_SECRET="your-api-secret"
export XFINANCE_API_URL="https://localhost:8087/api/v1"
export XFINANCE_TIMEOUT=30
export XFINANCE_MAX_RETRIES=3
```

### Programmatic Configuration

```python
from xfinance_sdk import XFinanceClient, Settings
from xfinance_sdk.config.retry_config import RetryConfig

# Using Settings class
settings = Settings(
    api_key="your-api-key",
    timeout=45,
    max_retries=4
)

client = XFinanceClient(settings=settings)

# Custom retry configuration
retry_config = RetryConfig(
    max_retries=5,
    backoff_factor=1.0,
    status_forcelist=(429, 500, 502, 503, 504)
)

client = XFinanceClient(api_key="your-api-key", retry_config=retry_config)
```
