00:00Welcome back. In this application we are building, we will also capitalize on APIs to request

00:14information from other applications, and that can make our application more capable and more

00:22advanced. And APIs are something that you will always use, or not always, but you will get to

00:29use a lot whenever you develop an application for yourself or for any project you have. So let's go

00:37ahead and give those APIs a shot and use them with our Vibe coding. Let me introduce what are APIs first

00:47in case you have not used them before. API stands for Application Programming Interface. So they are

00:56basically like a digital waiter that lets two apps or systems talk to each other. And so when your app

01:06needs an information or a piece of information, like the weather, fun fact, or a photo, it sends a request

01:15to another service through the API. The API then brings back the data your app asked for, so you can use it

01:26without needing to build everything from scratch. And so in this application we're going to be building,

01:34we're going to use the cat API. And that's a fun API that is out there that we can use to request images of cats.

01:46And so I want you to go to the catapi.com and then get your API key. So you're going to go click on get your API

02:00key. You're going to go get the free version again. You're going to write your email. You're going to write

02:07some app description. You'll have it for personal. And then in your email, you will get an API key.

02:16API key. And an API key is basically something private that you will keep. It's going to be unique

02:25to you. And it will allow you to request a service from the cat API. And so in this project, we're going

02:39to use that. It's going to be all fun. But then later on, we're going to use other types of APIs as well

02:45to integrate tools like generative AI or image generation or audio production, etc. So for now, go to the cat

02:58API and request your free API key.
