    How to use MarketStack API

    To use MarketStack API, you need to create an account on MarketStack. You can simply navigate to the sign up page and create a new free account.

    Once you have created your account, MarketStack will generate an API key for you. Make sure that you don’t share it with unauthorized users.

    Let’s call a simple API to observe how it works.

    Here is a sample API to check various exchanges and their details around the world.

    http://api.marketstack.com/v1/exchanges?access_key=YOUR_ACCESS_KEY

    Once you hit the request, you should get the following response instantly.


    GeSHi Error: GeSHi could not find the language json (using path /var/www/html/wp-content/plugins/codecolorer/lib/geshi/) (code 2)

    Awesome. It works.

    At present, MarketStack provides the following set of data.

    • End-of-Day Data: Get daily stock market data.
    • Intraday Data: Get intraday and real-time market data.
    • Tickers: Get information about stock ticker symbols.
    • Exchanges: Get information about all supported exchanges.
    • Currencies: Get information about all supported currencies.
    • Timezones: Get information about all supported timezones.

    You can check out the documentation of MarketStack for more details.

    Integrating with Node.js

    Here is a sample code to Integrate MarketStack API’s with Node.js.

    First, install axios.

    Replace the access key with your access key in the code shown below.

    const params = {
      access_key: 'YOUR_ACCESS_KEY'
    }

    axios.get('http://api.marketstack.com/v1/tickers/aapl/eod', {params})
      .then(response => {
        const apiResponse = response.data;
        console.log(apiResponse);
      }).catch(error => {
        console.log(error);
      });

    Save the file and run the code using the following command.
