Changing text dynamically from API

Design help CMS

I want to change a text field from the following API:

I am super new to dynamic content and how to use API. Can anyone guide me in a direction where I can learn how to do this?

This is the node.js HTTP code:

const http = require("https");

const options = {
	"method": "GET",
	"hostname": "apidojo-yahoo-finance-v1.p.rapidapi.com",
	"port": null,
	"path": "/market/v2/get-quotes?region=US&symbols=AAPL",
	"headers": {
		"x-rapidapi-key": "7a5cd29679mshb549165914a2ddap184d38jsn09428ffb2903",
		"x-rapidapi-host": "apidojo-yahoo-finance-v1.p.rapidapi.com",
		"useQueryString": true
	}
};

const req = http.request(options, function (res) {
	const chunks = [];

	res.on("data", function (chunk) {
		chunks.push(chunk);
	});

	res.on("end", function () {
		const body = Buffer.concat(chunks);
		console.log(body.toString());
	});
});

req.end();
