REST Countries offers RESTful endpoints to fetch detailed country information, including ISO codes, capitals, populations, currencies, languages, borders, time zones, and flag URLs. Key endpoints include /all (list all countries), /name/{country} (search by name), /alpha/{code} (ISO 3166-1 code), and /region/{region} (filter by region).
