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.
