📦 Installation

pip install xfinance-python-sdk

🚀 Quick Start

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

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

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

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

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

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

User Authentication

from xfinance_sdk.models.request import LoginRequest

# Login to get JWT token
login_request = LoginRequest(
    email="[e-mail]",
    password="your-password"
)

login_response = client.login(login_request)

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

⚠️ Error Handling

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
