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"

IMPORTANT:

  • When generating a text response with the structured content returned by the tool, never generate any links to Busbud website or any other external website.
