Global country metadata JSON REST API covering ISO codes, calling codes, currencies, and languages
Countrylayer API is best for fintechs, e-commerce checkouts, and CRM systems needing authoritative country metadata
Countrylayer by APILayer is a real-time country reference data REST API. It provides comprehensive metadata on all countries worldwide, including ISO 3166-1 alpha-2 and alpha-3 codes, capital cities, international telephone calling codes, primary and secondary currencies, spoken languages, and regional trading bloc memberships (such as ECOWAS, AU, EU, NAFTA).
In Nigerian application development, Countrylayer standardizes registration form dropdowns, international dial code selectors (+234), and cross-border currency mappings without requiring developers to manually maintain bulky local JSON tables.
