Advice on learning about bringing in outside sources via OpenAPI 3.1

[DigitalDanCreates]

Hello,

New to AEM, Can someone suggest training/ book so I can teach myself how to bring in data via Open API into an AEM Page? 

The data doesn't need an API key, and is available via Rest API.  Is it possible to bring in responses directly without an intermediary server?

Create a HttpClient connection for API inside Sling Models, Service, or Servlet to be passed to the page based on your requirement.
