Using the Apify API, here are some things that you can build:

• A web scraper that can extract data from websites and store it in a format of your choice
• An automated bot that can carry out tasks on your behalf, such as order products or copy data from one application to another
• A tool to monitor websites for changes and notify you when they occur
• A platform to run computationally intensive tasks, such as image and video processing, machine learning or scientific simulations
