Reittiopas API Developer’s Guide

Helsinki Regional Transport Authority (HSL) offers access right to Reittiopas (Journey Planner) interface for applications and services that support public transport usage and transport information availability. There are three possible ways to access the timetable and route data:

Use of these interfaces is free of charge. Distribution and re-use of HSL information is allowed. Due to limited service capacity, queries from each account are limited to max. 5000 weighted queries per hour. Documentation is available only in English and HSL takes no responsibility of possible errors or damages caused by documentation. If you find an error or have an idea how to improve the documentation, please tell us via the contact form.

Access to the interfaces is granted via the account registration form or if you need more information, please use the contact form. HSL reserves a right to inspect applications and services before granting access to the interface. HSL may revoke access rights whenever necessary, for example in case of excessive traffic to the interface or misuse of the service.
