Linz Public Transport

Query Linz Linien raw EFA endpoints for stop lookup and live departures. Use when tasks involve Linz public transport stop search, resolving stop IDs from stop names, or fetching upcoming departures from a stop.

Use this skill to interact with Linz Linien EFA endpoints:

• GET /efa/XML_STOPFINDER_REQUEST
• GET /efa/XML_DM_REQUEST

Read endpoint details in {baseDir}/references/endpoints.md before implementation. Use {baseDir}/scripts/linz_transport.py as the default execution path.

Workflow

1. Resolve the API base URL.
2. Run the script subcommand that matches the task.
3. Return a compact, user-facing summary.

Primary Tooling

• Script path: {baseDir}/scripts/linz_transport.py
• Runtime: Python 3, standard library only.
• Base URL input:
  • --base-url <url> argument, or
  • LINZ_TRANSPORT_API_BASE_URL environment variable, or
  • default http://www.linzag.at/linz2.

Preferred commands:

• Search stops:
  • python {baseDir}/scripts/linz_transport.py stops "taubenmarkt"
• Fetch departures by stop ID:
  • python {baseDir}/scripts/linz_transport.py departures --stop-id 60501160 --limit 10
• Resolve stop and fetch departures in one call:
  • python {baseDir}/scripts/linz_transport.py next "taubenmarkt" --limit 10 --pick-first

Step 1: Resolve Base URL

• Use user-provided base URL first.
• Otherwise use LINZ_TRANSPORT_API_BASE_URL if available.
• If neither exists, use http://www.linzag.at/linz2.

Step 2: Present Output

• Sort by countdownInMinutes ascending if needed.
• Show the next 5-10 departures unless user asks for more.
• Include both relative (countdownInMinutes) and absolute (time) times.
• Keep field names stable when returning JSON.

Error Handling

• If stop search returns empty list, suggest nearby spellings and retry with a shorter query token.
• If multiple stop matches are returned, rerun with explicit --stop-id or use next ... --pick-first only when ambiguity is acceptable.
• If departures response is empty, state that no upcoming departures are currently available.
• If HTTP request fails, report status code, endpoint, and retry guidance.
• If EFA response includes a message code, include that code in diagnostics.

Minimal Examples

bash

python {baseDir}/scripts/linz_transport.py stops "taubenmarkt"
python {baseDir}/scripts/linz_transport.py departures --stop-id 60501160 --limit 10
python {baseDir}/scripts/linz_transport.py next "taubenmarkt" --limit 10 --pick-first

powershell

python "{baseDir}/scripts/linz_transport.py" stops "taubenmarkt"
python "{baseDir}/scripts/linz_transport.py" departures --stop-id 60501160 --limit 10
python "{baseDir}/scripts/linz_transport.py" next "taubenmarkt" --limit 10 --pick-first
