Is doorfarer live?

Yes — it answered the hub's last check (checked 4h ago). It answered 100% of checks over the last 30 days.

Is doorfarer free to use?

Yes — the hub reached it with no key and no payment.

What tools does doorfarer have?

4 tools: find_trips, send_feedback, price_calendar, trip_details.

Is doorfarer safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• find_trips unknown 4h ago

  Finds the best round trips from where someone lives, not just from one airport: it adds the train or bus to every airport they can reach and ranks all options door to door, by price, by total travel time, or balanced. Use it when someone wants flights from their home town, could fly from several airports, or asks for the cheapest or fastest way to get somewhere, e.g. "I live in New Haven: should I fly to Lisbon from JFK, Newark, Boston or Hartford?" Not for a search from one airport already chosen. For a one-way trip set one_way (the trip length is then ignored). Multi-city: search each leg as one_way only when the user gave dates for it; otherwise ask for the dates. Set mode only when the user says how they get to the airport (car, train, bus, any): by default a home in the US compares driving, a taxi to a near airport and public transport, and a home elsewhere uses the train or bus. A named departure airport is an ordinary search: pass it as from_airports, with the home town the user gave. A month or holiday without a year means the next one coming; don't ask which year, and don't ask for the trip length or to confirm a town: search, and the answer says what it assumed. Any town or village works. The first search from a town we haven't seen takes about 20 seconds while we look up its train and bus connections; tell the user you're checking the connections from their town to each airport. Later searches from that town take a second or two. Give the home town and where to: airport, city or country codes, a list of them, or a region such as "Iberia" or "Southeast Asia". For "anywhere", a continent ("Asia") or "somewhere warm" it finds the cheapest places itself: pass "anywhere", "abroad" (another country) or the continent, or for warm, sunny or a beach the countries that fit the season with anywhere true; it searches the best 6 cities door to door. Dates are optional, but `dates` says where they came from: use "assumed" when the user gave none and you picked them (or left them out). Without them it searches departures in the next 3 months at 2-14 nights and says so. If the user gave no hint of when at all, one quick question about timing is fine. Example call: {"home": "New Haven", "destinations": ["LIS"], "dates": "from_user", "depart_from": "2027-03-01", "depart_to": "2027-03-31", "nights_min": 5, "nights_max": 9, "travellers": 2}. Show the answer's rows as a table with the airports each trip flies from and to, and give every booking link exactly as returned, as a clickable link (don't shorten or rewrite it); show the picks and at most a few more rows, and relay the answer's notes. Airports more than 8.5 hours from the door are left out and named in the answer (max_ground_hours changes that: set it only if the user says how far they would travel). Say when a ground leg is an estimate. If the answer's status isn't "ok", tell the user plainly what its note says and don't invent prices. Keep the user's own dates, trip length and places: if nothing is found, say so and offer to widen them, instead of widening on your own. Prices are in the traveller's home currency unless `currency` is given, per person; use the totals the answer gives for a party and don't convert or add up prices yourself. Prices come from recent searches on Aviasales and can change. Booking links are affiliate links: Doorfarer may earn a commission if you book, at no extra cost to you. Say so when you show them, and only then. When the user picks a trip, trip_details gives it step by step with a calendar file; when they ask which month is cheapest, price_calendar answers first, instantly. If an answer is wrong or confusing, report it with send_feedback.

• send_feedback unknown never probed

  Tell Doorfarer's maker where Doorfarer fell short, so it can be fixed. Use it when a find_trips answer was wrong, confusing, or missing something you needed to help, or when the user asks you to pass something on. Write as the assistant that used the tool: what you asked for, what came back, what you expected instead. The report is about Doorfarer only, never about the user: leave out names, contact details, travel plans, reasons for travelling and anything the user said about themselves. Be specific and honest, including when the problem may have been your own call. Pass the search_id from the answer's last line. One report per search. If the user asked you to report something, tell them it's sent.

• price_calendar unknown 4h ago

  Shows the cheapest month to travel from someone's home town to a place, for each airport within reach: what fares on each route usually cost per month (from the fares Doorfarer has seen, not live prices) plus the train or bus to the airport. Instant. Use it when the user's dates are flexible or they ask when it's cheapest to go; then call find_trips for the month they choose to get bookable trips. Needs the home town; months as "2027-03", at most 12. Prices per person, in the home currency unless `currency` is given.

Also gives the booking link and a calendar file (.ics) the user can add. Pass a trip id from the find_trips answer ("Trip ids, row by row", or a row's `id`). Use it when the user picks a trip or asks how the journey works. Ids are kept for 72 hours.
