 ## Project Overview
 
-The Apify SDK for Python (`apify` package on PyPI) is the official library for creating [Apify Actors](https://docs.apify.com/platform/actors) in Python. It provides Actor lifecycle management, storage access (datasets, key-value stores, request queues), event handling, proxy configuration, and pay-per-event charging. It builds on top of the [Crawlee](https://crawlee.dev/python) web scraping framework and the [Apify API Client](https://docs.apify.com/api/client/python). Supports Python 3.11–3.14. Build system: hatchling.
