Angular 7 return one json object from web api and access on page

I can successfully query an API and return a JSON list and then iterate through the list within my HTML page.

I have another part of my API that returns one result and I am struggling getting the data to show on the page.

If I have the following method:

getonofflinegt1():Observable<any>{
        return this.httpclient.get("https://localhost:44359/api/tagdetail/mytag");
    }

Which returns the following (it will always be 1):

{"tagname":"mytag", "value":"99"}

what data type do I pass it too and then how do I access it on the screen?

For the list I assign it to the following:

lstonoffline:mytags[];

and then iterate through the list using ngFor
