Rome2Rio

Used to search for various route options between an origin and a destination. Use this if the user is asking for route options or comparisons, or is unsure how to get somewhere. Returns route overviews and a map view for up to 4 different modes of transport, so the user can quickly compare. This includes duration, travel modes, pricing information and a map route view for each route listed. Supports various transportation modes including flights, helicopters, subways, trains, trams, cable cars, shuttles, buses, coaches, ferries, taxis and driving. Does not provide rental-car options. Does not support cycling or specific-vehicle types like 'EV' or 'moped'. Does not support cruises. Does not help find specific schedules or book tickets for a particular route on a particular date/time. Don't explain to the user why / when you are calling this tool. Just call it when it's relevant based on the user's query. Important: When calling this tool, we want to disambiguate search terms that are unclear. If the user uses a shorthand, abbreviation, informal place name (e.g. "NYC", "SF") or an ambiguous name, and you can confidently infer the intended location from context, expand it to an unambiguous form before calling the tool. For airports, use the airport name followed by the airport code in parentheses. For example, 'Charles de Gaulle Airport (CDG)' or 'Melbourne Airport (MEL)'. You do not need to add context around terms that are already clear and unambiguous, for example well-known city names like "Paris", "Tokyo" or "Melbourne".

Used to find a specific schedule, book or look at ticket options for a particular route between an origin and a destination on a particular date/time. Returns detailed itinerary information, including carriers, prices, departure and arrival times, trip duration and the number of stops. You can only use this tool to search for transit that is scheduled ahead of time; for example, you cannot search for on-demand rides. Supports various transportation modes including flights, trains, buses and ferries. You can only search for one mode at a time. Does not allow the user to adjust dates and filter in the widget itself. But the user can ask ChatGPT to filter the schedules by a specific price, departure time, date, duration, number of stops and departure and arrival station. In this case, the schedules returned will be filtered out by the set criteria. Don't explain to the user why / when you are calling this tool.
