google_flights_deals_search

Discover cheap flight destinations from an origin via SerpAPI's Google Flights Deals engine (google_flights_deals). Unlike google_flights_search there is no arrival_id — the engine explores destinations for you — and there are no pagination or navigation tokens. Dates accept a single YYYY-MM-DD or a 'start,end' range (e.g. '2026-06-27,2026-07-03') to widen the window. Supports round trip (type=1, needs return_date) and one way (type=2). Prices are in `currency` (default USD). Result shape: { source, fetchedAt, query, search_metadata, search_parameters, departure_informations, deals: [...] } — the list key is `deals` (there are no best_flights/other_flights here). Each deal: { destination_id, name, country, price, average_price, discount_percentage, flight_link, serpapi_flight_link, thumbnail, outbound_date, return_date, departure_airport_code, arrival_airport_code, flight_duration, stops, airline, airline_code, description, highlights }. The dates are `outbound_date` / `return_date` (YYYY-MM-DD) — the live engine returns those, not the `start_date`/`end_date` of SerpAPI's docs — and a deal carries NO departure or return time.

glstring

Country code for the search, e.g. 'us', 'uk', 'de'.

hlstring

Language code, e.g. 'en', 'es', 'fr'.

typeinteger

Trip type: 1 = round trip (default, needs return_date), 2 = one way.

stopsinteger

Max stops: 0 = any (default), 1 = nonstop only, 2 = 1 stop or fewer, 3 = 2 stops or fewer.

adultsinteger

Number of adults. Default 1.

childreninteger

Number of children. Default 0.

currencystring

Currency of returned prices (ISO code, e.g. 'USD', 'EUR'). Default USD.

no_cacheboolean

Force a fresh SerpAPI fetch and bypass this server's result cache. Default false.

max_priceinteger

Maximum ticket price in the selected currency.

zero_traceboolean

Enterprise-only ZeroTrace mode: don't store search params/metadata on SerpAPI. Default false.

return_datestring

Return date as a single YYYY-MM-DD, or a 'start,end' range. Required when type=1 (round trip). When outbound_date is a range it must be a 'start,end' range too (or drop it and use trip_length/travel_duration).

trip_lengthstring

Trip length in days: a single number, or a 'min,max' day range (e.g. '3,5').

departure_idstring

Departure AIRPORT IATA code(s) (3-letter, uppercase, e.g. 'WAW' or 'WAW,WMI') or a Google location kgmid (/m/… or /g/…). Comma-separate multiple. NOT a city/metro code (NYC, LON, PAR return no results — list the airports). No arrival_id: the deals engine discovers destinations for you.

max_durationinteger

Maximum total trip duration in minutes (e.g. 1500 for 25h).

travel_classinteger

Travel class: 1 = economy (default), 2 = premium economy, 3 = business, 4 = first.

outbound_datestring

Outbound date as a single YYYY-MM-DD, or a 'start,end' range (e.g. '2026-06-27,2026-07-03') to search a window.

infants_on_lapinteger

Number of infants on lap. Default 0.

infants_in_seatinteger

Number of infants in seat. Default 0.

travel_durationinteger

Travel duration preset: 1 = one week, 2 = weekend, 3 = two weeks.

exclude_airlinesstring

Exclude these airlines: comma-separated 2-letter IATA codes, or an alliance (STAR_ALLIANCE, SKYTEAM, ONEWORLD). Mutually exclusive with include_airlines.

include_airlinesstring

Only these airlines: comma-separated 2-letter IATA codes, or an alliance: STAR_ALLIANCE, SKYTEAM, ONEWORLD. Mutually exclusive with exclude_airlines.

google_flights_search

Search Google Flights live via SerpAPI. Returns best_flights and other_flights (each with legs, airlines, times, duration, layovers, price and carbon emissions), plus price_insights and airport info. Supports round trip (type=1, needs return_date), one way (type=2) and multi-city (type=3 via multi_city_json). Two-step flows: pass a departure_token from a prior result to get the returning flights / next leg, or a booking_token to get booking options — re-send the original search params alongside either token. Prices are in `currency` (default USD). IDs are AIRPORT codes, never city/metro codes: TYO, NYC, LON, PAR, MIL, ROM, OSA, CHI, WAS return NO results (live-verified) — send the airports instead (TYO → 'HND,NRT'; NYC → 'JFK,EWR,LGA'; LON → 'LHR,LGW,STN,LTN'; PAR → 'CDG,ORY'; MIL → 'MXP,LIN,BGY'; ROM → 'FCO,CIA') or the city's Google kgmid (e.g. '/m/07dfk' for Tokyo). Result shape: { note?, source, fetchedAt, query, search_metadata: { google_flights_url }, search_parameters, best_flights: [...], other_flights: [...], price_insights, airports } — the two itinerary lists are `best_flights` and `other_flights` (there is no `flights` or `deals` key at the top level, and an itinerary is never a bare flight). Each itinerary: { flights: [{ departure_airport: { name, id, time }, arrival_airport: { name, id, time }, duration, airplane, airline, airline_logo, travel_class, flight_number, legroom, extensions }], layovers: [{ duration, name, id, overnight }], total_duration, carbon_emissions, price, type, airline_logo, departure_token, booking_token } — `price` is the whole-itinerary price in `currency`, `duration`/`total_duration` are minutes, and the per-leg times are local 'YYYY-MM-DD HH:MM' strings. Feed `departure_token` back for the return leg and `booking_token` for booking options. A top-level `note` appears only when stops=1 found no nonstop flight and the server retried without the stop filter: the itineraries are then connecting flights, and their tokens need the same params re-sent without `stops` — tell the user that no direct flights were found and connecting flights are shown.
