In this video, we will understand what an API is and also create a simple API using Django REST Framework in Python.

So. What is an API?

API stands for Application Programming Interface. API basically helps one web application to communicate with another application. Let’s try to understand this with an example.

Let’s assume you are developing an android application which has feature
to detect the name of a famous person in an image. In order to achieve this
you have 2 options.
Option 1 is to collect the images of all the famous personalities around the
world, build a machine learning/deep learning or whatever model it is and use it in your application.

Option 2 – Just use someone else’s model using API to add this feature in your application.
Large companies like Google and Microsoft may have images of all famous
personalities. So they would already have built a model which can recognize
these images. You can just use their API to send the image and get back the name of the person in that image.

You will not know what logic/code they have written inside and how they have
trained the model. You will only be given an API (or an url). It works like a black box where you send your request (in our case its the image), and you get the response ( which is the name of the person in that image).

Now that you know what API is, let us create a simple API using django REST
Framework in python.
