1. Wikimedia provides a web API that we can use to access Wikipedia data. To learn more about how to use this API, see: https://en.wikipedia.org/api/rest_v1/
2. This page helps you construct URLs to make specific API calls. You can expand the section you are interested in, fill in the form and click on the Try it Out button to see what results you will get from a call. For our example, we are going to use the summary page example. On the Wikimedia REST API documentation page, first expand Page Content.
