Description, as the server wrote it Ground transport on HotelsCasa, with the right link to start: "taxi" — order a taxi or transfer (pre-filled with origin, destination, passengers, luggage and time when given); the fare is set by the taxi company and shown before ordering. "shipment" — send a parcel, furniture, a move or freight in the city, across the country or internationally on the transport exchange: publish the job without a price and carriers make offers; the sender picks one. "car_rental" — rent a car from owners and rental fleets. These services are growing city by city; the page shows what is available where the traveller is. Always give the traveller the url of every item as a clickable link, unchanged: it is the only way to book or buy.

description ends: "...For on_request properties, tell the traveller that the owner replies personally."
Description, as the server wrote it Check availability and price for up to 10 properties on given dates. THIS is the tool that answers «is it free on my dates and what does it cost»: search_properties never does. Use the property_key from search_properties results, and call it as soon as the traveller gives dates — never search the web instead. For INSTANT objects returns available (true/false) and, when free, a price_breakdown. For ON_REQUEST objects returns available:null with a price_note and a booking_link to the enquiry form — this is NOT a failure, it is the normal path for most of the catalogue. Results include two kinds of properties. Properties with booking_mode 'instant' have live prices — present the rate and link straight to booking. Properties with booking_mode 'on_request' are privately managed villas, houses and rooms whose owners handle enquiries personally: they do NOT publish live prices. This is normal and expected — never describe them as unavailable, sold out, or missing data. Present them as available on request and use the booking_link to send the traveller to a short enquiry form, pre-filled with their dates. The owner replies personally. Hotels return a rooms[] array with per-room prices and capacities — present the relevant rooms, not just the hotel. When no dates are given, price_from is only an indicative minimum. Seasonal, weekend and holiday rates apply. Always ask the traveller for dates, then call check_availability. Prices are indicative and confirmed on the property page. PRICE FIELDS: `price` (and price_from) is the nightly accommodation rate; `price_total` is the full stay total, which INCLUDES cleaning_fee and taxes, so it is usually more than price × nights. Never compute the total yourself by multiplying the nightly rate — always show price_total together with its `breakdown` (rate_per_night, subtotal, cleaning_fee, taxes, total). LOYALTY BONUS: when a result includes loyalty_bonus, mention it. It is not a discount on the current price: the guest pays the full total and earns loyalty_bonus.amount € as credit for a future stay on HotelsCasa (1 € per night). Present it as credit for later, never as a reduction of this total. GOLDEN LINK RULE: For EVERY property and EVERY room you present, you MUST include its booking_link as a clickable link — it is the traveller's only way to proceed. Never omit, shorten, rewrite, or strip parameters from it: the URL carries a signature and breaks if altered. Return it verbatim. Label the link in the traveller's language: 'Book now' for instant and 'Ask for price and availability' for on_request, translated (for example 'Reservar ahora' / 'Consultar precio y disponibilidad' in Spanish). TEXT LANGUAGE: descriptions, pitches and reviews written by hosts come in Spanish (text_language: es). Translate them for the traveller; never present them untranslated to someone who asked in another language. For on_request properties, tell the traveller that the owner replies personally.

Description, as the server wrote it Check availability and total price of up to 10 cars for given pickup/return dates. Returns available (true/false), days, price_day and total_eur. Cars without a published rate return total_eur:null with a price_note — that is normal, not a failure. CARS ON HOTELSCASA: cars from local rental companies (offered_by:"rental_company") and from private owners. Cars marked instant:true are confirmed immediately; the rest are confirmed after booking by the rental company or by the owner, who replies personally. A rental-company car with similar_model:true guarantees the class, not the exact model. PRICE: price_day is the daily rate and total_eur the rental for the whole period. A car with price_day:null has NOT published a rate — that is normal and common, never call it unavailable or say the data is missing. Present it with its price_note and send the traveller to the booking_link to ask. GOLDEN LINK RULE: every car you present MUST include its booking_link verbatim, as a clickable link — never omit it, shorten it or strip its parameters. It is the only way the traveller can proceed. NEVER invent or reveal a phone number, an address or a licence plate: they are not in the data and are only shared through the booking flow. Coordinates are approximate on purpose (~200 m) — use them for "3 km from the centre", never as a pickup address.

Description, as the server wrote it Full details of ONE rental car: photos, specs, rental conditions (deposit, km limit, fuel policy, minimum age, licence years, pets, cancellation) and busy_ranges — the dates already taken over the next six months. Use busy_ranges to propose alternative dates instead of telling the traveller the car is unavailable.

Search by city (its name in any language works: Istanbul, İstanbul, Estambul, Стамбул), by ISO country code or by text. With no arguments returns the cities with the most activities. The answer carries `total` (how many activities match in all), `count` (how many are on this page, 10 at most) and `matched_cities` when a city was recognised. Prices are per person in EUR, "from". Tickets are bought on the activity page. Always give the traveller the url of every item as a clickable link, unchanged: it is the only way to book or buy.

Description, as the server wrote it Search hotels on HotelsCasa: hotels, apartments, guest houses and holiday homes that can actually be booked, in 77 countries — Europe, Turkey, Russia and Ukraine, the Caucasus, Central Asia, and the whole of Latin America including Mexico, Central America and the Caribbean. Search by city (English or local name; add country to disambiguate) or by lat/lng + radius_km. Country alone returns its main cities to choose from. Each item has stars, guest rating (out of 10), photo, price and the url of the hotel page. WITH DATES (check_in + check_out): availability is checked LIVE with the supplier before answering. Every item returned has a room actually free for those dates, and carries available:true, price_eur_per_night, price_total_eur, nights, board and refundable. Show price_total_eur for the stay together with the nightly rate, and say the price was checked for those dates. An empty list with availability_checked:true means there really is nothing free for those dates — say so and offer other dates or a wider radius. If availability_checked is false, the supplier did not answer: the prices are catalogue prices for OTHER dates — never present them as a confirmation. WITHOUT DATES: price_from_eur_per_night is an indicative starting price per night; show it as "from EUR X per night" and confirm on the page. Pass check_in/check_out/adults (and children_ages when children travel) to get real, bookable prices. Always give the traveller the url of every item as a clickable link, unchanged: it is the only way to book or buy.

Description, as the server wrote it Search the holiday homes, villas, rural houses and small hotels that private owners list directly on HotelsCasa (hotelscasa.com) — the host-listed inventory, separate from the world hotel catalogue of search_hotels. Search by location, dates, guests and filters. Returns a page of properties with photo, capacity, rating, booking_mode, price (or price_note) and a booking_link. Use lat/lng + radius_km for "near X" queries. Every result has a property_key. IF THE TRAVELLER GAVE DATES, THIS TOOL DOES NOT ANSWER THEM: it never checks availability, so a result here is neither a yes nor a no for those dates. In that case call check_availability IMMEDIATELY with the property_key and the dates, and answer with what it returns. Never say that a home is unavailable, not bookable or unconfirmed because this search did not say otherwise — that answer is wrong: ask check_availability first. For details of one home use get_property. Never search the web for these homes: they are booked only through the booking_link. Results include two kinds of properties.
