Metal Price API – Copper, Aluminum, Lithium & Industrial Metals in JSON

A metal price API provides structured access to real-time and historical metal price data, including copper, aluminum, lithium, nickel, steel, cobalt, and other industrial metals. These materials play a key role in manufacturing, construction, energy systems, electric vehicles, and global supply chains.

This guide explains how metal price data works, how it is structured in APIs, and how developers use it in industrial dashboards, commodity analytics, procurement systems, and financial applications.

In practice, metal price data is used to monitor market movements, compare industrial commodity prices, analyze supply chain risks, and track long-term demand across major metal markets.

Typical Industrial Metals Data Structure

Metal price data is usually delivered as structured JSON objects. Each record represents a single price snapshot for a specific metal or industrial commodity.

A typical metal price response includes the following parameters:

• commodity_name – metal or commodity identifier
• commodity_unit – measurement unit such as USD per ton, pound, or ounce
• commodity_price – latest quoted price
• price_change_day – daily price change
• percentage_day – daily percentage change
• percentage_week – weekly percentage change
• percentage_month – monthly percentage change
• percentage_year – yearly percentage change
• datetime – timestamp of the price update

This structure allows developers to compare multiple metals in one system, build price dashboards, and integrate industrial commodity data into business workflows.

Key Metals Covered by Metal Price APIs

Metal price APIs can cover a broad set of industrial, precious, and battery-related metals. The most common use cases focus on metals that affect manufacturing costs, infrastructure projects, and energy transition supply chains.

Copper

Copper prices are widely followed because copper is used in electrical wiring, construction, electronics, and renewable energy infrastructure. As a result, many analysts use copper as a signal for industrial demand.

Aluminum

Aluminum price data is important for transportation, packaging, aerospace, construction, and manufacturing. Because aluminum is lightweight and widely used, price changes can affect many industrial supply chains.

Lithium

Lithium is a critical battery metal used in electric vehicles, energy storage, and electronics. Therefore, lithium price data is especially important for EV, battery, and clean energy market analysis.

Nickel and Cobalt

Nickel and cobalt are also important battery metals. They are used in energy storage, stainless steel, and high-performance industrial materials.

Steel and Iron Ore

Steel and iron ore prices are closely connected to construction, manufacturing, infrastructure spending, and global industrial activity.

How Metal Price Data Is Used

Metal price data supports many industrial, financial, and operational workflows.

Manufacturing Cost Tracking

Manufacturers use metal prices to monitor raw material costs and adjust procurement plans. For example, changes in aluminum or steel prices can directly affect production budgets.

Battery Metals Analytics

Battery and EV companies track lithium, nickel, and cobalt prices to understand input costs, supply chain pressure, and long-term demand trends.

Commodity Trading and Research

Traders and analysts use copper, aluminum, and other metal prices to evaluate industrial momentum, inflation pressure, and commodity market trends.

Supply Chain Monitoring

Procurement teams and logistics platforms use metal price data to monitor cost volatility and prepare for changes in supplier pricing.

Below is an example of how multiple metal prices may appear in JSON format.

{
  "output": [
    {
      "commodity_name": "copper",
      "commodity_unit": "usd/lb",
      "commodity_price": "6.16",
      "price_change_day": "0.03",
      "percentage_day": "0.63%",
      "datetime": "2026-05-11T12:00:00.000"
    },
    {

    }
  ]
}

Example Metal Data Request

To retrieve metal price data, you can send a simple API request. For example, the following request retrieves copper data:

https://apidata.fin2dev.com/v1/commodities?key=YOUR_API_KEY&commodity_name=copper

---

Example API Integration

The following examples show how developers can request copper price data using Python and PHP.

Python Example

import requests

url = "https://apidata.fin2dev.com/v1/commodities"
params = {"key":"YOUR_API_KEY","commodity_name":"copper"}

data = requests.get(url, params=params).json()

print(data["result"]["output"])

PHP Example

<?php

$url = "https://apidata.fin2dev.com/v1/commodities?key=YOUR_API_KEY&commodity_name=copper";

$response = file_get_contents($url);
$data = json_decode($response, true);

print_r($data["result"]["output"]);

?>

Live Data Example

For example, a compact response from a metal price API may include the output field with current price data for a selected metal.

{
  "output": [
    {
      "commodity_name": "copper",
      "commodity_unit": "usd/lbs",
      "commodity_price": "6.1602",
      "price_change_day": "0.03",
      "percentage_day": "0.63%",
      "percentage_week": "2.18%",
      "percentage_month": "4.91%",
      "percentage_year": "18.72%",
      "datetime": "2026-05-11T12:00:00.000"
    }
  ]
}

Metal Price API vs Commodity Price API

A metal price API focuses on industrial and metal-related commodities such as copper, aluminum, lithium, nickel, steel, cobalt, and other raw materials. Meanwhile, a broader Commodity Price API provides access to metals, energy, precious metals, agriculture, and other commodity markets.

If your application focuses only on metals, a metal-focused integration may be enough. However, for multi-asset systems, a full commodity API provides more flexibility.

Related Commodity APIs

Metal price data is often used alongside other commodity APIs to build broader market data platforms, procurement tools, and analytics systems.

• Gold Price API – access real-time gold price data and XAU market data
• Silver Price API – track silver price movements and XAG market data
• Oil Price API – monitor crude oil prices, WTI, and Brent market data
• Natural Gas Price API – access real-time natural gas prices and energy market data
