• Selfservice API Integration - Access customer, account, and service data
• Multi-Service Support - Electricity and Gas service integration
• Clean Architecture - Modular design with separate OAuth and API clients
• Type Safety - Full type hints for better IDE support
• Comprehensive Error Handling - Detailed exceptions for different error scenarios
• Flexible Configuration - Environment variable support with sensible defaults

Installation

pip install pymercury

Quick Start

Simple Authentication

from pymercury import authenticate

# Get OAuth tokens
tokens = authenticate("[e-mail]", "your-password")
print(f"Customer ID: {tokens.customer_id}")
print(f"Access Token: {tokens.access_token}")

Complete Account Data

from pymercury import get_complete_data

# Get everything in one call
data = get_complete_data("[e-mail]", "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)

from pymercury import MercuryClient

# Create client and login
client = MercuryClient("[e-mail]", "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

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

# OAuth authentication only
oauth_client = MercuryOAuthClient("[e-mail]", "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

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}")

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)
monthly_electricity = api_client.get_electricity_usage_monthly(customer_id, account_id, service_id)
if monthly_electricity:
    print(f"Monthly Usage Period: {monthly_electricity.start_date} to {monthly_electricity.end_date}")
    print(f"Total Monthly Usage: {monthly_electricity.total_usage} kWh")

# Get electricity usage content (disclaimer, modal info, etc.)

    print(f"Locale: {gas_content.locale}")                       # "en"
    print(f"Usage Disclaimer: {gas_content.disclaimer_usage}")   # Gas billing info
    print(f"Modal Title: {gas_content.usage_info_modal_title}")  # "USAGE GRAPH KEY"
