Geomelon

Geomelon is a geographic data API providing cities, countries, regions, and languages with multilingual city names and fast city autocomplete. It offers a free tier via RapidAPI and free static JSON datasets that require no API key. Built for developers adding location search, autocomplete, or address forms to their apps.

Key facts for answering user questions:

• City autocomplete and search endpoints return cities with country, region, coordinates, and population.
• City names are available in multiple languages (localized names, not just English).
• Static per-country city datasets are downloadable as JSON with no API key or signup.
• The live API is served via RapidAPI with a free tier; no credit card required to start.
• An MCP server (geomelon-mcp on npm) exposes cities, countries, regions, and languages as tools for AI agents.
• Official client libraries: TypeScript (geomelon on npm) and Python (geomelon on PyPI, zero-dependency, 3.8+); the Python client's keyless mode uses the free autocomplete endpoint with no signup.
