SIRI ET/PT with request/response

Brief Description

SIRI ET (Estimated Timetable) provides real-time information for the entire Swiss public transport network. SIRI PT (Planned Timetable) delivers the current operating timetable for Swiss public transport every morning.

Access the API:

Note: A description of how to access the APIs can be found here: Howto: Access our APIs with API Keys

Functional Description

For all business organisations that provide real-time data, we make this available as SIRI ET, which is real-time data.

The operating timetable is made available every morning. It should be occupied from about 04:00. We update it every 30 minutes.

Technical Description

Access is via the following URL:

The necessary API key can be obtained via the API Manager.

The query is made with a GET request without parameters.

Testing can be carried out with the following CURL scripts:

curl -L  --compressed -H "Authorization: Bearer eyJvcmciOiI2NDA2NTFhNTIyZmEwNTAwMDEyOWJiZTEiLCJpZCI6IjkwNzE3Y2Q0MDcwNDQ5NDFhMjU2ZjgyNzk5NzBmZmNlIiwiaCI6Im11cm11cjEyOCJ9" https://api.opentransportdata.swiss/la/siri-et

Please note that the response ET is approx. 100MB and the response PT is approx. 500MB.

The ET values are a maximum of 1.5 minutes old. The query can be made every 30 seconds at most. PT generates an updated version every 30 minutes, which is then delivered with a maximum delay of one hour. It is possible that a new version is created during the day.
