Quick Start

import asyncio
from cozi_client import CoziClient
from models import ListType, ItemStatus

async def main():
    async with CoziClient() as client:
        # Authenticate
        await client.authenticate("your_username", "your_password")
        
        # Create a shopping list
        shopping_list = await client.create_list("Groceries", ListType.SHOPPING)
        
        # Add items to the list
        await client.add_item(shopping_list.id, "Milk")
        await client.add_item(shopping_list.id, "Bread")
        
        # Get all lists
        lists = await client.get_lists()
        for lst in lists:
            print(f"List: {lst.name} ({lst.type.value})")

asyncio.run(main())
