I have now found a working way to do this through Curl. Here is an example:
curl -X POST -H “Content-Type: application/graphql” -H “ET-Client-Name: xxxx-yyyyy” --data ‘{quay(id:“NSR:Quay:6548”){id name estimatedCalls(timeRange: 3600, numberOfDepartures: 2){expectedDepartureTime}}}’ https://api.entur.org/journeyplanner/2.0/index/graphql
This query returns json-formatted data about when the two next departures from a specified “Quay” leave. A quay seems to be track related to stop. So, outside my house, I have one stop, and two directions. So, for me, I chose the “quay” going towards town, as that is the one I am interested in.
I used the url “example” from EnTur to find my stop: https://api.entur.org/api/geocoder/1.1/autocomplete?text=**_Aln_**&categories=NO_FILTER&focus.point.lat=59.91&focus.point.lon=10.76&lang=en
Change the text to math your stop name, and you should be able to find your own stop.
Then you can use the example called “avgangstavle på et stoppested” from Entur – nasjonal reiseplanlegger to find your quay numbers. (Replace stopPlace ID and remove startTime to rather use “now” instead of specific time.)
