Web Resources

Don't reinvent the wheel!

Need a complicated secondary function? Want to run a few tests? There are plenty of APIs, datasets, and other resources available online for you to use so you can focus on more important parts of your project! We've compiled a list below, but note that this page contains only a small subset of what's available for developers; if you can't find what you want, try searching for your own!

What is an API? An Application Programming Interface (API) is a software intermediary that allows an application to access another Web-based software application. You may want to use an API to retrieve data or perform functions that you wouldn't want to program from scratch.

Are all these resources free? Most are, but some do require payment. However, we've tried not to include anything outrageously expensive!
