Introduction

The PeruAPIs package provides a unified interface to access open data from the World Bank API, Nager.Date API, and the REST Countries API, with a focus on Peru. It allows users to retrieve up-to-date or historical information on topics such as economic indicators, demographics, national holidays, and key geopolitical details.

In addition to API-access functions, the package includes a curated collection of open datasets related to Peru. These datasets cover a wide range of topics including administrative divisions, electoral data, demographics, biodiversity and educational classifications.

PeruAPIs is designed to support users working with data related to Peru by integrating international RESTful APIs with structured and reliable datasets from public, academic, and government sources into a single, easy-to-use R package. This makes the package a valuable tool for reproducible research, teaching, and policy analysis.
