Summary

In this chapter, we took a detailed look at the term API. In Chapter 3, Creating Your First Deep Learning Web Application, we saw how an API can be written in Python using Flask and we saw how to use that API in a web application. We now know how an API is different from a language library and how important it is to make use of APIs. We became familiar with a variety of deep learning APIs that are offered by some top-notch organizations. 

As we progress through the upcoming chapters, we will see how to use these APIs to build powerful and intelligent web applications. We will start with the deep learning APIs provided by Google Cloud Platform in the next chapter.
