Wikipedia is the largest and most-read reference work in history. It was ranked the 7th most popular site in 2022 and hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations.
Being one of the best free online sources for information, Wikipedia gave you APIs to fetch the data yourselves. But learning how to use those APIs may take weeks or months to master. In this article, we'll see how to use Golang API wrapper Go-wiki to access and fetch a variety of information from the Wikipedia website.
