GoldAPI.io JavaScript Example: Live Gold Price API with Vanilla JS

This repository shows how to call the GoldAPI.io live gold price API using vanilla JavaScript and the native Node.js fetch API. It is a small, dependency-free example for fetching the current XAU/USD gold price with a GoldAPI.io API token.

Use this example if you are looking for:

• GoldAPI.io JavaScript example code
• Live gold price API integration in Node.js
• XAU/USD API request sample
• Vanilla JavaScript fetch example for precious metals prices
• Gold price API quickstart for GitHub projects

API Endpoint

The example calls the GoldAPI.io endpoint:

https://www.goldapi.io/api/XAU/USD

Equivalent curl request:

curl -X GET "https://www.goldapi.io/api/XAU/USD" \
  -H "x-access-token: GOLD_API_TOKEN"

Requirements

• Node.js 18 or newer
• A GoldAPI.io API token

Node.js 18+ is used because it includes native fetch, so no third-party HTTP client is required.

Quick Start

Clone the repository and run:

GOLD_API_TOKEN=your_goldapi_token_here npm start

Optional values:

GOLD_API_TOKEN=your_goldapi_token_here GOLD_API_METAL=XAU GOLD_API_CURRENCY=USD npm start

JavaScript Example

The core request is implemented in index.js:

const response = await fetch("https://www.goldapi.io/api/XAU/USD", {
  method: "GET",
  headers: {
    "x-access-token": process.env.GOLD_API_TOKEN,
  },
});

const data = await response.json();
console.log(data);
