Understanding the World Bank API

There are a lot of APIs exposed by the World Bank (http://www.worldbank.org/) and the API documentation can be found here (https://datahelpdesk.worldbank.org/knowledgebase/articles/889386-developer-information-overview). Out of the available APIs, we will use the Indicator APIs (https://datahelpdesk.worldbank.org/knowledgebase/articles/898599-api-indicator-queries), which represent information such as total population, GDP, GNI, energy use, and much more.

Using the Indicator API, we will fetch the GDP information for the countries available in the database for the last 10 years. Let's look at the API's REST URL and the data returned by the API, as follows:

GET http://api.worldbank.org/countries/BR/indicators/NY.GDP.MKTP.CD?format=json&date=2007:2017 ...
