“Getting a data science job would have been much harder without Dataquest. It’s a great product. I recommend it to anyone who asks me about how to get started.”
Although there are many datasets available in convenient formats like CSVs, there is also a large amount of data that is accessible only via an API. If you want to analyze streaming data from Twitter, for example, or dig into posting trends on Reddit, you need to get that data from the relevant APIs.
In this course, you’ll learn the fundamentals of APIs, such as connecting to an open API and interpreting different status codes. You’ll also learn how to work with the JSON data format in R (since most data from APIs will be in JSON format). Then, you’ll tackle more complex tasks like authenticating with private APIs and submitting more complex requests.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. The course concludes with a guided project that asks you to assemble a full data analysis project using an API to get data on New York’s solar energy resources.
