Available tools
search_hotels
Search for hotels by location and dates with cash AND points pricing. Returns hotels with side-by-side cash vs points rates, cents-per-point (CPP) valuation, and deal scores so you can recommend the best value. This is Gondola's unique advantage — no other travel search shows both cash and points rates together. Args: location: City name, address, or area to search (e.g. "Tokyo", "Manhattan, New York", "near LAX airport"). checkin: Check-in date in YYYY-MM-DD format (e.g. "2026-04-15"). checkout: Check-out date in YYYY-MM-DD format (e.g. "2026-04-20"). num_adults: Number of adult guests. Defaults to 2. chain_name: Optional hotel chain to filter by (e.g. "marriott", "hilton", "hyatt", "ihg"). Case-insensitive substring match against each result's chain. If nothing matches, the unfiltered results are returned with an explicit note so you don't keep retrying. loyalty_programs: Optional list of the user's loyalty programs (e.g. ["hilton_honors", "marriott_bonvoy"]). When provided, results include personalized earnings and tier benefits like 5th night free. loyalty_points: Optional dict of program name to points balance (e.g. {"hilton_honors": 250000}). When provided, results indicate whether the user can afford each hotel with points. limit: Max number of hotels to return (default 20). The response notes how many more exist and how to narrow; raise this only when the user explicitly wants a longer list. Returns: Formatted list of hotels with cash rates, points rates, CPP valuation, and deal recommendations.
get_hotel_details
Get detailed information, room types, and rates for a specific hotel. Use this after search_hotels to get full details for a hotel the user is interested in. Returns room options with pricing, cancellation policies, and amenities. Args: hotel_id: The hotel's Vervotech property ID (returned by search_hotels). checkin: Check-in date in YYYY-MM-DD format. checkout: Check-out date in YYYY-MM-DD format. num_adults: Number of adult guests. Defaults to 2. Returns: Detailed hotel information including rooms, rates, policies, and amenities.
compare_rates
Compare cash vs points rates across multiple hotels side-by-side. Use this after search_hotels to help a user decide between their top hotel picks. Returns a comparison table with cash rate, points rate, CPP valuation, and value signals for each hotel, highlighting the best cash value and best points value. Args: hotel_ids: List of hotel IDs to compare (max 5). Get these from search_hotels results. checkin: Check-in date in YYYY-MM-DD format. checkout: Check-out date in YYYY-MM-DD format. num_adults: Number of adult guests. Defaults to 2. Returns: Side-by-side comparison of cash vs points rates with recommendations.
get_booking_link
Get booking options for a hotel. Presents two explicit booking paths so the path is settled up front rather than discovered mid-conversation: 1. **Check out on Gondola** with a booking link — always available. 2. **Book here now** with an eligible saved card — shown only when the user has a card that can be charged in chat, and referenced by its last 4. Anonymous users get path 1 plus a prompt to sign up for in-chat booking. Use this after search_hotels or get_hotel_details when a user wants to book. Pass ``gondola_rate_id`` whenever a specific rate has been surfaced (from get_hotel_details or compare_rates) so the link lands on that rate's checkout page instead of the generic hotel page. Args: hotel_id: The hotel's Vervotech property ID (from search_hotels results). checkin: Check-in date in YYYY-MM-DD format. checkout: Check-out date in YYYY-MM-DD format. num_adults: Number of adult guests. Defaults to 2. children_ages: Comma-separated ages of children (e.g. "5,8"). Empty string if no children. gondola_rate_id: Optional rate ID from get_hotel_details/compare_rates. When provided, the link deep-links straight to that rate's checkout page. Returns: Booking instructions tailored to the user's auth status.
book_hotel
Book a hotel room using a rate from get_hotel_details. Requires a Gondola account (API key) and a saved payment method. Use get_payment_methods to find your payment ID. The gondola_rate_id comes from the room rates returned by get_hotel_details — each room option has a rate ID you can use here. Guest details (given_name, family_name, email_address, phone_number) can either be passed directly or prefilled from a saved travel profile: pass travel_profile_id (from get_travel_profiles) to book "as <traveler>" without collecting each field. Any field you also pass explicitly overrides the profile. To earn points and elite credit, pass loyalty_account_id — use the Member Number from get_loyalty_accounts that matches the hotel's chain (e.g. the World of Hyatt account for a Hyatt property). When a loyalty_account_id is passed, the booking goes out under the email registered to that membership (overriding any travel profile or email_address), so the stay credits to the right account. Args: gondola_rate_id: The rate ID from get_hotel_details room rates. payment_id: Payment method ID from get_payment_methods. given_name: Guest's first name (optional if travel_profile_id is provided). family_name: Guest's last name (optional if travel_profile_id is provided). email_address: Guest's email for confirmation (optional if travel_profile_id is provided). phone_number: Guest's phone number with country code (optional if travel_profile_id is provided). special_request: Optional special request for the hotel (e.g. "high floor", "late check-in"). loyalty_account_id: Optional Member Number (from get_loyalty_accounts) to earn points. travel_profile_id: Optional travel profile ID (from get_travel_profiles) to prefill guest details.
