Now that we know how to use streams and serialization,

we can use our new knowledge to send and receive data on the Internet.

This is where serialization is especially helpful,

because we can take our objects, package them up, and send them to somewhere else.

We can also ask for the data on rapid by deserializing and

then use it in our program.

There are lots of APIs available on the web for us to play around with.

In this series of videos,

we'll be using a couple of web APIs from Microsoft's Cognitive Services.

Most web APIs these days require some kind of authentication to prevent people from

firing off millions of requests and bogging down their servers.

So, to follow along, you'll need to sign up for

a free Microsoft account if you haven't already.

Then we'll need to get API keys for use with our web requests.

Instructions to do this are included in the notes.
