# IDFM Journey (PRIM/Navitia)
Use the bundled script to call PRIM/Navitia endpoints without extra dependencies.
## Prereqs
- Set `IDFM_PRIM_API_KEY` in the environment before running.
## Quick commands
Run from anywhere (path is inside the skill folder):
- Resolve places (best match + list):
- `python3 scripts/idfm.py places "Ivry-sur-Seine" --count 5`
- Journeys (free-text from/to; resolves place ids first):
- `python3 scripts/idfm.py journeys --from "Ivry-sur-Seine" --to "Boulainvilliers" --count 3`
- Incidents / disruptions (by line id or filter):
- `python3 scripts/idfm.py incidents --line-id line:IDFM:C01727`
- `python3 scripts/idfm.py incidents --filter 'disruption.status=active'`
Add `--json` to print raw API output.
## Notes
- If place resolution is ambiguous, increase `--count` and choose the right `stop_area` id.
- For API details and examples, read: `references/idfm-prim.md`.
