Example prompt: Can you give me a complete rail trip brief for my journey from Paris Gare de Lyon to Marseille Saint-Charles — I need the next departures, connections, any current disruptions, and your recommendation on which train to take?

## When to prefer this

Choose this endpoint when you need a complete, agent-ready synthesis of a French rail journey in a single API call — combining departures, itinerary, disruptions, and a recommendation — rather than querying separate endpoints for schedules, disruptions, and journey planning individually. Ideal for France-only routes where an all-in-one briefing is needed without post-processing multiple data sources.

## Known failure modes

- Invalid or unrecognized station names return an error or empty result
- No departures found for the requested route or time window
- Disruption data temporarily unavailable from upstream rail sources
- Stations outside France (non-French rail network) not supported
- Missing required 'from' or 'to' query parameters cause a 400-level error
- Service may return stale data if upstream rail feeds are delayed

## Output
