Scandinavia Transit Skill

Search ground transport (trains, buses, ferries) within Norway, Sweden, and Denmark using their national transit APIs.

• Entur (Norway) — Open GraphQL API for all Norwegian transit
• ResRobot (Sweden) — REST API via Trafiklab for all Swedish transit
• Rejseplanen (Denmark) — REST API (HAFAS) for all Danish transit including pricing

Norway: Entur (Journey Planner v3)

Open GraphQL API. No key needed (but a client name header is required). Covers ALL Norwegian transit: Vy trains, buses, ferries, trams, metro. 60+ operators.

Trip Search (Oslo to Bergen example)

curl -s -X POST "https://api.entur.io/journey-planner/v3/graphql" \
  -H "Content-Type: application/json" \
  -H "ET-Client-Name: $ENTUR_CLIENT_NAME" \
  -d '{"query": "{ trip(from: {place: \"NSR:StopPlace:59872\"}, to: {place: \"NSR:StopPlace:548\"}, numTripPatterns: 5) { tripPatterns { startTime duration legs { mode expectedStartTime expectedEndTime fromPlace { name } toPlace { name } line { publicCode name authority { name } } } } } }"}' | jq '.data.trip.tripPatterns[] | {start: .startTime, duration_min: (.duration / 60), legs: [.legs[] | {mode: .mode, from: .fromPlace.name, to: .toPlace.name, line: .line.publicCode, operator: .line.authority.name, depart: .expectedStartTime, arrive: .expectedEndTime}]}'

Find Stop IDs

Stop IDs use the format NSR:StopPlace:XXXXX. Find them via the Geocoder:

curl -s "https://api.entur.io/geocoder/v1/autocomplete?text=Oslo%20S&size=3" \
  -H "ET-Client-Name: $ENTUR_CLIENT_NAME" | jq '[.features[] | {name: .properties.name, id: .properties.id, type: .properties.layer}]'

Key Stop IDs

Use the Geocoder to find any stop. Works for airports, ferry terminals, bus stops too.

Departure Board

curl -s -X POST "https://api.entur.io/journey-planner/v3/graphql" \
  -H "Content-Type: application/json" \
  -H "ET-Client-Name: $ENTUR_CLIENT_NAME" \
  -d '{"query": "{ stopPlace(id: \"NSR:StopPlace:59872\") { name estimatedCalls(numberOfDepartures: 10) { expectedDepartureTime destinationDisplay { frontText } serviceJourney { journeyPattern { line { publicCode name transportMode } } } } } }"}' | jq '.data.stopPlace | {name: .name, departures: [.estimatedCalls[] | {time: .expectedDepartureTime, destination: .destinationDisplay.frontText, line: .serviceJourney.journeyPattern.line.publicCode, mode: .serviceJourney.journeyPattern.line.transportMode}]}'

Notes

• GraphQL API. POST only. One endpoint: https://api.entur.io/journey-planner/v3/graphql
• Set ET-Client-Name header on all requests.
• No rate limit key, but respectful usage expected.
• Schema explorer: https://api.entur.io/graphql-explorer/journey-planner-v3
• Covers some cross-border routes into Sweden via Vy and SJ Nord.

Cross-Border Routes

When to Use

Load this skill when:

• Planning train/bus/ferry routes between Scandinavian cities
• Checking schedules and durations for ground transport
• Finding stop IDs for trip planning
• Comparing train vs flight for intra-Scandinavia legs
• Looking up Danish transit fares/zones
• Checking real-time disruptions (himsearch)
• Tracking live vehicle positions (journeypos)

Do not:

• Use for booking (search/schedule only)
• Use for flights (use Seats.aero, SerpAPI, or Duffel)
• Expect pricing from Entur or ResRobot (only Rejseplanen has pricing)

Search Workflows

1. "How do I get from A to B?"

Step 1: Pick API by country (Norway=Entur, Sweden=ResRobot, Denmark=Rejseplanen, cross-border=both).

Step 2: Find stop IDs:

# Norway
curl -s "https://api.entur.io/geocoder/v1/autocomplete?text=Flåm&size=3" \
  -H "ET-Client-Name: $ENTUR_CLIENT_NAME" | jq '[.features[] | {name: .properties.name, id: .properties.id}]'

# Sweden
curl -s "https://api.resrobot.se/v2.1/location.name?input=Malmö&format=json&accessId=$RESROBOT_API_KEY" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId}] | .[0:5]'

# Denmark
curl -s "https://www.rejseplanen.dk/api/location.name?accessId=$REJSEPLANEN_API_KEY&input=Svendborg&format=json&type=S&lang=en" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId}] | .[0:5]'

Step 3: Trip search with date and time. Step 4 (Denmark): Add tariff=1 for pricing.

2. "What trains leave from X?"

curl -s "https://www.rejseplanen.dk/api/departureBoard?accessId=$REJSEPLANEN_API_KEY&id=8600626&duration=120&products=31&format=json&lang=en" | jq '[.DepartureBoard.Departure[] | {time: .time, name: .name, direction: .direction, track: .track}]'

3. "What's near me?"

curl -s "https://www.rejseplanen.dk/api/location.nearbystops?accessId=$REJSEPLANEN_API_KEY&originCoordLat=55.6736&originCoordLong=12.5681&r=500&format=json&lang=en" | jq '[.stopLocationOrCoordLocation[] | .StopLocation | {name: .name, id: .extId, dist: .dist}]'

Or nearbyDepartureBoard to skip stop lookup.

4. "What ferry to Ærø?"

curl -s "https://www.rejseplanen.dk/api/trip?accessId=$REJSEPLANEN_API_KEY&originId=100200261&destId=100200222&date=2026-08-28&time=08:00&format=json&lang=en" | jq '[.TripList.Trip[] | {legs: [.LegList.Leg[] | {name: .name, from: .Origin.name, to: .Destination.name, depTime: .Origin.time, arrTime: .Destination.time}]}] | .[0:5]'

5. "I know the train number."

trainSearch to find it, then journeyDetail with the ref for full stops.

6. "What can I reach in 2 hours?"

curl -s "https://www.rejseplanen.dk/api/reachability?accessId=$REJSEPLANEN_API_KEY&originId=8600626&duration=120&maxChange=2&format=json" | jq '.'

7. "Any disruptions?"

curl -s "https://www.rejseplanen.dk/api/himsearch?accessId=$REJSEPLANEN_API_KEY&format=json&lang=en" | jq '.'

8. Multi-country trips

Search from both ends. Øresund trains appear in both ResRobot and Rejseplanen.

Tips

• Always format=json. Always lang=en for Rejseplanen.
• Use extId (numeric) for queries, not the long HAFAS id string.
• Check rtTime/rtDate for delays.
• passlist=1 shows intermediate stops.
• maxChange=0 for direct connections only.
• Page with numF/numB or context scroll tokens.
• Product bitmask is additive. Omit for all types.
