# Scandinavia Transit Skill

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

**Sources:**
- [Entur (Norway)](https://developer.entur.org) — Open GraphQL API for all Norwegian transit
- [ResRobot (Sweden)](https://www.trafiklab.se/api/trafiklab-apis/resrobot-v21/) — REST API via Trafiklab for all Swedish transit
- [Rejseplanen (Denmark)](https://labs.rejseplanen.dk) — 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)

```bash
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:

```bash
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

| City | Stop ID | Name |
|------|---------|------|
| Oslo S | NSR:StopPlace:59872 | Oslo S |
| Bergen | NSR:StopPlace:548 | Bergen stasjon |
| Stavanger | NSR:StopPlace:4130 | Stavanger |
| Trondheim | NSR:StopPlace:41742 | Trondheim S |
| Bodo | NSR:StopPlace:49484 | Bodo stasjon |

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

### Departure Board

```bash
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.

## Sweden: ResRobot v2.1

## Cross-Border Routes

| Route | Covered By | Notes |
|-------|------------|-------|
| Oslo to Stockholm | Entur + ResRobot | SJ trains, ~6 hours |
| Malmö to Copenhagen | ResRobot + Rejseplanen | Øresund trains, 35 min |
| Gothenburg to Oslo | Entur + ResRobot | Vy/SJ, ~4 hours |
| Stockholm to Copenhagen | ResRobot | SJ/DSB, ~5 hours via Malmö |
| Copenhagen to Malmö | Rejseplanen | Øresund trains from Danish side |

## 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:

```bash
# 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?"

```bash
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?"

```bash
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?"

```bash
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?"

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

### 7. "Any disruptions?"

```bash
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.
