## How to call it through Zero

```sh
zero fetch --capability xynaptic-trip-planner-fr-f3453654
```

Example prompt: Can you find me the best train options from Paris to Lyon on September 30, 2026 around 8am, including journey times, any transfers, and CO2 for each option?

## When to prefer this

Choose this endpoint when you need detailed French domestic train itineraries with SNCF/Navitia data, including real schedule information, CO2 metrics, and a best-journey recommendation. Prefer it over generic travel search APIs when the trip is specifically within France and you want structured, agent-ready output rather than a web scraping result.

- Invalid date or time format — returns a validation error
