Languages API

healthy 3,602 Subscribers

A clean reference for the world’s languages. Look up any language by its ISO 639-1 (two-letter) or ISO 639-2 (three-letter) code or by name, search by English or native name, list every language with an optional right-to-left filter, or group languages by family. Each entry includes the ISO codes, English and native names, language family, a right-to-left flag and a Wikipedia link. Built on the open ISO 639 dataset and served entirely in-memory, so responses are instant and the service is always available. Ideal for internationalization and localization, language pickers and selectors, content tagging and developer tooling.
