Using what you have learnt about HTTP request and REST APIs, in today's project you will build a website that uses data from a public API.
For example, previously we create a rain alert app using a weather API. We also created an ISS tracker and looking into Bitcoin prices, all using a public API.
Today, you get to work on an API that you find interesting and build a service or website based on that API.
Here are some example APIs:
New York Subway Data
Elephant Data
Barcode Generator/Recognition
Stock Market Data
Harry Potter Data
Art Data
Dictionary API
ESPN Data
Food Facts API
Brewery Data
Spelling and Grammar Check API
Sound Effects API
Lord of the Rings API
