country_info: Get information about countries

In countries: Deal with Country Data in an Easy Way

Get information about countries

Description

This function is an interface for REST Countries API. It allows to request and download information about countries, such as: currency, capital city, language spoken, flag, neighbouring countries, and much more. NOTE: From 2026, a personal key is needed to use the API, the key can be created on the API website REST Countries API. Internet access is needed to download information from the API. At times the API may be unstable or slow to respond. Every time this function is executied it performs three API calls (the entire dataset is downloaded in three batches).

Usage

country_info(
  key,
  countries = NULL,
  fields = NULL,
  fuzzy_match = TRUE,
  match_info = FALSE,
  base_url = "https://api.restcountries.com/countries/v5"
)

Arguments

key	String containing the personal API key used to authenticate the user. The key can be created on the API website REST Countries API.
countries	(optional) A vector of countries for which we wish to filter the downloaded information. The function also supports fuzzy matching capabilities to facilitate filtering. When left blank or set to NULL, all the countries in the dataset are returned.
fields	(optional) Character vector indicating the fields to query. If fields is left empty, all available fields will be returned. A description of the accepted fields can be found on the API website or it can be obtained with the function list_fields().
fuzzy_match	Logical value indicating whether to allow fuzzy matching of country names. Default is TRUE.
match_info	Logical value indicating whether to return information on country names matched to each input in countries. If TRUE, two additional columns will be added to the output (matched_country and is_country). Default is FALSE.

Examples

# Run examples only if a connection to the API is available:
if (check_countries_api(warnings = FALSE)){

# NOTE: A VALID KEY IS NEEDED TO RUN THE EXAMPLES. CREATE ONE AT https://restcountries.com/

# downloaded all the available information by leaving both countries and fields arguments empty
# The example below uses a test key (it will return a fixed output for Canada only)
info <- country_info(key = "rc_live_demo")

# The example below filters the dataset to obtain information for one or more countries:
# info <- country_info(countries = "DR Congo", key = "YOUR_KEY")
# info <- country_info(countries = c("Morocco", "Brazil", "FR"), key = "YOUR_KEY")

# The fields argument can be used to query only for specific information
# info <- country_info(fields = "capitals", key = "YOUR_KEY")
# info <- country_info(countries = c("Brazil", "USA", "FR"), fields = "capitals", key = "YOUR_KEY")
