Whenever you work with a 3rd party API, you always have to be aware that their documentation page sometimes changes. Part of your job as a developer is to stay on top of these changes and adapt to any updates that they may have. This is why the more dependencies you have in your projects, the more likely it is for your project to break or need updating. For now, I have added the API docs and information that you will need the rest of this project so you can always use them as a reference:

Face Detection model we will be using: https://www.clarifai.com/models/face-detection

How we will use the API with JS (don't worry I will show you the easy way to do this): https://github.com/Clarifai/clarifai-javascript#basic-use

Finally, this is the list of all the models you can use with this API if you want to customize your project: https://www.clarifai.com/model-gallery
