Reverse Geocoding API to retrieve city name from latitude and longitude coordinates

Overview

GeoDataSource provides a RESTful reverse geocoding API that converts latitude and longitude coordinates into detailed location information, including city names. Its main endpoint accepts lat/lng parameters and returns JSON responses with structured data like city, region, country code, postal code, and time zone. Ideal for apps needing to display user-friendly location names from GPS data—such as weather apps, delivery trackers, or travel platforms. The API supports global coverage and integrates easily with web and mobile applications via standard HTTP requests.
