Countries API

A fast, fully offline-grade countries reference API backed by a bundled ~250-country dataset.

Every returned country is enriched with ready-to-use flag image URLs (PNG + SVG via flagcdn.com) and normalized international calling codes. Look up by ISO code (cca2/cca3/ccn3/cioc), search by name, or filter by region, currency, language or dialing code. No upstream calls, no rate-limit risk.
