Using Google App Scripts/Sheets for a website CMS / REST API

Question

Is it possible to use either Google Apps Script or the Google Sheets API to host a REST API, so that I can make client-side content requests on a static web page? If so, how would I go about this?

I'm building a simple website hosted on GitHub, and I want to experiment with using a spreadsheet as a content management system, eg fetching a running list of projects with corresponding text, images, etc.

Forgive me if I completely misunderstood the capabilities of either/both of these applications, or overlooked a previous ask!

You can use the Sheets API with multiple languages.

Here you have the different quickstarts that show you how to do it: https://developers.google.com/sheets/api/guides/concepts

Also you can create a Web App with Apps Script and embed it in your website: https://developers.google.com/apps-script/guides/web
