About Geomelon

Geomelon is a read-only REST API for geographic reference data, covering cities, countries, and regions with multilingual name support. It provides city search across 200,000+ cities with filtering by population, country, or region, sorting, pagination, and localized names via a preferredLanguages parameter. It also returns country metadata such as ISO codes, telephone codes, driving side, and head of state, along with administrative regions per country. Responses are JSON and use stable UUID identifiers. The API is hosted on RapidAPI, and TypeScript and Python client libraries are available (npm install geomelon, pip install geomelon), along with an MCP server and an n8n community node.

The service also offers a free autocomplete endpoint at oneshot.geomelon.dev that requires no API key, serving pre-built JSON files scoped by country and language for city-name prefix search. This endpoint covers 203 countries and 50 languages, totaling 2,497 country-language pairs.

Geomelon is intended for applications that need structured, accurate location data without maintaining their own geographic database.
