How to Use a Free Commodities Price API in Web & Mobile Apps

Imagine that you are creating a new fintech application. Your users wish to know the price of gold or crude oil in real time. When your data is slow, your users lose money.

Scraping websites manually to get the prices of commodities is a nightmare. It is slow, not reliable, and scales poorly. You require one API that can get you to global markets in real time.

This guide will teach you how to use a free commodities price api to drive your projects. We shall discuss API authentication and integration. Back-end price services will also be discussed.

This walkthrough will work regardless of whether you are creating a commodities dashboard or some sort of price tracker. Let us get down to the technicalities. Get your app linked to live data.

How to Get Started with API Authentication

First of all, you have to register with a good company such as CommodityPriceAPI. They offer a free commodities price api tier. It is ideal for development.

Step 1: Obtain Your API Key

Register on the platform in order to obtain your unique key. This is an important key in API authentication. In its absence, the server will give an error on all requests.

Step 2: Set Up Your Backend

Always keep your key secret. Do not put it in a client-side JavaScript commodity price API code. Fetched data is used by sending it to your frontend using backend price services.

Step 3: Test the Connection

Use a basic tool such as cURL or Postman for a free commodities price api. Make a request to the most recent rates endpoint. Confirm that the price and the timestamp information are returning properly.

Let's try it out practically.

You must study the chosen API before integrating it into your system. It will give you an idea of pricing, endpoints, and other features. This will ensure that the API matches your project perfectly or not.

Once you have done this step, the next step is to create an account to get your API key. Remember, the API key is a unique secret for every user. Therefore, you must not share it with anyone. After creating an account, you will be able to sign in. It will bring you to a dashboard. Here, you will see an API key like the one given below:

Once you have the API key, the next step is to choose your endpoint. Commodity prices API gives you access to the following endpoints:

You can access the complete documentation here.

Let's say we choose the latest endpoint:

$ curl "https://api.commoditypriceapi.com/v2/rates/latest?symbols=xau,wtioil-fut" -H "x-api-key: YOUR_API_KEY"

It comes with the following JSON response:

{
  "success": true,
  "timestamp": 1703866777,
  "rates": {
    "WTIOIL-FUT": 72.29,
    "XAU": 2066.98
  },
  "metaData": {
    "XAU": {
      "unit": "T.oz",
      "quote": "USD"
    },
    "WTIOIL-FUT": {
      "unit": "Bbl",
      "quote": "USD"
    }
  }
}

Let's move to the technical integration step now:

Technical Integration: JavaScript Commodity Price API Example

Let us consider some examples of a commodity API. JSON is supported in most programming languages. JavaScript reigns as the King of web app price integration.

The API Request Flow

1. Your server receives a request from the client.
2. The call to the free commodities price api is made by your server.
3. The API gives real time commodity prices.
4. The message is reverted to the client by your server.

// Example: Fetching latest rates for Gold and Crude Oil

const apiKey = 'YOUR_API_KEY';

const symbols = 'XAU,WTIOIL-FUT';

const url = `https://api.commoditypriceapi.com/v2/rates/latest?apiKey=${apiKey}&symbols=${symbols}`;

async function getCommodityData() {

  try {

    const response = await fetch(url);

    const data = await response.json();

    if (data.success) {

      console.log("Current Prices:", data.rates);

    } else {

      console.log("Error:", data.error.message);

    }

  } catch (err) {

    console.error("Connection failed", err);

  }

}

Here is the output

Current Prices: {
  XAU: 2034.56,
  "WTIOIL-FUT": 78.42
}

In this code snippet, there is a seamless integration. It manages the query, verifies success, and then processes the data.

Please note that you can choose the programming languages or tech stacks that match your existing applications.

Displaying Data in Mobile and Web Apps

In the case of mobile app commodity prices, everything is performance. You cannot afford to lose volume on mobile data. At this point, price data caching is critical.

Best Practices for Using a Free Commodities Price API

There is a strategy for using a free commodities price api. You would like to maintain your quota and offer recent information.

Implement Price Data Caching

Do not make the api call with each refresh of the user. Cache the price locally within 60 seconds. This will decrease your usage and also accelerate the delivery of the message.

Handle Errors Gracefully

In some cases, a symbol may be obsolete. You should deal with the 404 SYMBOLNOTFOUND error in your code. Always give a default value or a useful message to the users.

Monitor Your Usage

Look at the dashboard on a regular basis. Your mobile app commodity pricing may have to go viral, and in this case, you may have to buy a more expensive plan. Financial institutions tend to take premium plans to eliminate the issues that may happen when a limit is reached.
