Google Flights Toolkit
Arcade toolkit that lets LLMs search and resolve flight itineraries via the SerpApi Google Flights API, covering one-way, round-trip, and multi-city travel.
Capabilities
- Airport lookup — Resolve city names, country names, or airport names to IATA codes, including metropolitan codes (e.g. NYC, LON) accepted by flight search tools.
- One-way & round-trip search — Search Google Flights for outbound-only or paired outbound/return itineraries in a single call; results include direct
google_flights_urlbooking links. - Multi-city search — Search open-jaw and multi-leg itineraries as a bundled query, which is typically cheaper than summing individual one-way fares.
- Booking option resolution — Resolve a
booking_tokenfrom any flight search to the airlines and OTAs selling that specific itinerary, with optional POST data for backend vendor hand-off.
Secrets
SERP_API_KEY — API key issued by SerpApi, the underlying data provider. To obtain one:
- Create or log in to an account at serpapi.com.
- Navigate to your dashboard and copy the API key shown under Your Private API Key.
- SerpApi requires a paid plan (or trial credits) to access Google Flights results; verify your plan includes the Google Flights engine.

|---|---|---|---|
Resolve a ``booking_token`` to the airlines and OTAs selling that itinerary.
Pass a ``booking_token`` returned by ``search_flights`` or
``search_multi_city_flights`` to get the vendors selling that
specific flight. The token encodes the route, dates, cabin class,
and passenger counts (every segment for multi-city), so there are
no ``travel_class``, ``num_adults``, or ``num_children`` parameters;
supplying a cabin or party size would silently disagree with the
itinerary the token was issued for.
Leave ``include_booking_post_data`` off (the default) when an LLM
is comparing prices; turn it on only when a backend needs to
rebuild the vendor hand-off, since the POST body is multiple
kilobytes per option. | 1 | ||
Find IATA airport codes for a city, country, or airport name.
Metropolitan codes (NYC, LON, TYO, PAR, ...) are accepted as a
``departure_airport_code`` or ``arrival_airport_code`` in flight
searches and mean "any airport in this city". | 1 | ||
Search Google Flights for one-way or round-trip itineraries.
For a trip where the traveler returns to their origin, issue a
single call with both ``outbound_date`` and ``return_date`` set.
Do NOT issue two separate one-way searches in opposite directions
and sum the prices: airlines price round-trip fares independently
from one-way fares, so the sum of two cheapest one-ways is rarely
equal to the cheapest round-trip and is typically more expensive.
Each returned itinerary carries a ``google_flights_url`` that opens
that specific pre-selected flight on Google Flights, so you can hand
the user a booking link straight from these results without a
separate booking-options lookup. | 1 | ||
Search Google Flights for a multi-city (open-jaw) itinerary.
Use this for trips that are neither a simple one-way nor a round-trip
(e.g. an open-jaw three-leg trip that ends back at the origin).
The open-jaw bundle is typically cheaper than the equivalent set
of one-way searches summed; never substitute multiple
``search_flights`` calls for a single multi-city query.
Each returned itinerary carries a ``google_flights_url`` that opens
that specific pre-selected itinerary on Google Flights, so you can
hand the user a booking link straight from these results without a
separate booking-options lookup. | 1 |
