Client for the 'World Bank' APIs.

worldbank

Overview

worldbank provides a simple interface to the following World Bank APIs:

• Indicators API v2
• Poverty and Inequality Platform (PIP) API
• Finances One API
• Projects API v2

The main difference to other packages is that it’s a modern implementation using the httr2 package and supports all available endpoints and parameters.

Installation

You can install the released version of worldbank from CRAN with:

install.packages("worldbank")

And the development version from GitHub with:

# install.packages("pak")
pak::pak("m-muecke/worldbank")

Usage

worldbank functions are prefixed with wb_ and follow the naming convention of the World Bank API v2.
