Gdynia City Open Data API

API

Open data API for Gdynia (Poland) municipal government datasets

Overview

The Gdynia City Open Data API provides access to official public datasets from Gdynia’s municipal government. It offers RESTful endpoints covering transportation (bus schedules, parking zones), urban planning (building permits, green spaces), environment (air quality, waste management), and public services (library hours, local events). Responses are primarily in JSON format, enabling easy integration into apps, research projects, or civic tech tools. Use cases include building resident-focused transit apps, analyzing urban development trends, or enhancing transparency in local governance.
