As we did in the previous chapter, to use this service, we will need to add it to our Microsoft Azure portal. Head over to https://portal.azure.com/ on your browser and log in (or register if you don't already have an account). 

Once logged in, you will be taken to your Dashboard; from here, click on the +New button at the top of the left panel. This will expand out a menu. Within this menu, search and click on AI + Cognitive Services, which will spawn another menu where we can select the Computer Vision API, as shown in the following screenshot:

After clicking on the Computer Vision API item, you will be presented with a tab requiring you to enter the details of your service, such as Name, Subscription, Location, Pricing tier, and Resource Group, and help is accessible within the user interface. With all that done, you have your service up and running; details of this service should be visible on the screen and can be accessed from your dashboard, as shown in the following screenshot:

To use your service, you will need to call it using the generated keys. These can be accessed by clicking on Show access keys... which, when clicked, will display a set of keys you will need. For convenience, copy and paste them somewhere easily accessible (Notepad) for use later in this chapter.
