Full Description

Search and compare bus, train, shuttle, and ferry schedules worldwide with comprehensive filters and transparent pricing. Results render in a rich, list view showing origin and destination stop as well as departure time, trip duration and price in the currency of the user's choice for side-by-side comparison.

Autoset guidance (server-side, case-insensitive intent detection):

  • Origin/Destination: ALWAYS disambiguate ambiguous locations (YOU MUST provide uniquely identifiable locations or airport codes). Always specify city name with state/province/region and country:

Examples: "Paris" → clarify "Paris, TX, USA" vs "Paris, TN, USA" vs "Paris, Ile-de-France, France" "London" → clarify "London, England, United Kingdom" vs "London, ON, Canada"

CRITICAL TEMPORAL RULES:

  • If current date is before requested date → prompt the user to use a date in the future
  • If requested month is before current month → use NEXT year
  • If today is 2025-12-15 and user asks "trips in January" → use 2026-01-01
  • For relative dates: "next week" → add 7 days, "next month" → add 1 month
  • When ambiguous, default to the NEAREST FUTURE occurrence that satisfies constraints

Examples (intent → autosets)

  • "Paris to London on June 1st 2026" -> origin_name="Paris, France" destination_name="London, UK" departure_date="2026-06-01"- "Montreal to London on January 1st 2026" -> origin_name="Montreal, QC, Canada" destination_name="London, ON, Canada" departure_date="2026-01-01"

Filtering

  • Modality filter: "Show me only train results" -> vehicle_types=["train"]
  • Modality filter: "Bus only" / "I want bus tickets" -> vehicle_types=["bus"] (use ["bus","shuttle","van"] for bus-like vehicles)
  • Modality filter: "Train and ferry" -> vehicle_types=["train","ferry"]
  • Time filter (times in departure's local timezone): "Departures before 3pm" -> departure_before="15:00"
  • Time filter: "Departures after 8am" / "Morning departures" -> departure_after="08:00"
  • Time filter: "Between 9am and 5pm" -> departure_after="09:00" departure_before="17:00"
  • Arrival filter (times in arrival/destination's local timezone): "Arrive before 6pm" -> arrival_before="18:00"
  • Arrival filter: "Arrive after noon" -> arrival_after="12:00"
  • Arrival filter: "Arrive between 2pm and 8pm" -> arrival_after="14:00" arrival_before="20:00"
  • Arrival filter for overnight trips: "Leaving after 1pm, arriving before 8am the next day" -> departure_after="13:00" arrival_before="08:00" arrival_date="YYYY-MM-DD" (next day)
  • Passenger count: "2 passengers" / "for 2 people" / "2 tickets" -> passenger_count=2
  • Conversation language: when the language of the conversation can be detected, set conversation_language to their language (ISO 639-1, e.g. "fr", "de") or locale (e.g. "fr-CA") so labels and copy match the conversation. Use the user's browsing location to determine the locale. Example: "fr-CA" if the latest message in the conversation is in french and the user browsing from Canada. "es-us" if the latest message in the conversation is in spanish and the user browsing from the United States.
