Transport for Czech Republic API
Overview
The IDOS API provides public transport connection search for the Czech Republic, covering buses, trains, and urban transit. No authentication is required for basic use, making it accessible for beginners. It is the primary route-planning API used by Czech transit applications.
Beginner Tip
No API key is required for basic queries. The API is primarily designed for connection searches between Czech cities — try searching for connections between Prague and Brno to see it in action.
