v6.db.transport.rest is a REST API for the public transportation system in Germany.
Because it wraps an API of Deutsche Bahn, it includes most of the long-distance and regional traffic, as well as some international trains and local buses. Essentially, it returns whatever data the DB Navigator app shows*, including realtime delays and disruptions.
When comparing results from this API to what the DB Navigator app shows there might be occasional differences due to them utilizing different, not 100% identical backends.

This API returns realtime data whenever it is upstream. The API for DB's mobile app provides it.

You can just use the API without authentication. There's a rate limit of 100 requests/minute set up.
This API has CORS enabled, so you can query it from any webpage.
This API sends ETag & Cache-Control headers, allowing clients cache responses properly.
