What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of sandbox.hotels402.com controls every word below.

Find and price hotels

Search hotel properties and price them for a stay in one call. Filter by place name and radius, full-text query, country and star rating. Check-in, check-out, party size, `maxPricePerNight` and its `currency` are REQUIRED: ask the guest for the first four before searching, because a call without them runs no search and answers with what is still to be asked. `currency` is the ISO 4217 code of the budget figure (`EUR` most of the time): use the one the guest already named rather than re-asking, and ask them only when they gave a bare number you cannot place. Send their own number and name its currency, never one you converted; every price in the answer comes back in that same currency, named back to you in the answer's own `currency` field — read that rather than assuming one. Ask about children with the party size and pass their ages in `childrenAges` — a child left out is priced as absent, and a child whose age is still `null` is refused until the age arrives. With them the answer comes back in two group

Book a room

Book a room `list_hotels` priced. Pass the `offerId` that room and rate came back with, exactly as given — it names the hotel, the room, the rate, the stay and the price, which is why none of those are separate arguments. It needs the guest's full name, email, phone and address, so ask for those once they have chosen. It answers one of two ways: a `confirmationNumber` means the room is booked and the guest pays the hotel at the desk, and a `paymentUrl` means the room is not held yet and that link is where the guest pays to get it booked. A handle expires after 30 minutes; call `list_hotels` again with that same `offerId` to re-price the one room rather than searching the whole property afresh. Where a rate's `cancelTerms` is null we hold no cancellation terms: say so, say the hotel's own terms apply and arrive with its confirmation, and book once the guest agrees on that basis. Public — no API key.
