Google Flights Toolkit
The Arcade Google Flights toolkit lets LLMs search live flight data and resolve booking options via the SerpApi Google Flights API — no OAuth required.
Capabilities
- Airport lookup — Resolve city names, country names, or airport names to IATA codes (including metropolitan codes like NYC or LON) for use in flight searches.
- One-way & round-trip search — Query Google Flights for one-way or round-trip itineraries in a single call; results include direct
google_flights_urllinks for immediate handoff to users. - Multi-city / open-jaw search — Search bundled multi-leg itineraries that are typically cheaper than equivalent summed one-way fares; also returns per-itinerary
google_flights_urllinks. - Booking option resolution — Convert a
booking_tokenfrom any flight search result into a list of airlines and OTAs selling that exact itinerary, with optional POST body data for backend vendor hand-off.
Secrets
SERP_API_KEY — A SerpApi API key used to authenticate all requests to the Google Flights endpoint. Obtain it by:
- Creating or signing in to an account at serpapi.com.
- Navigating to your SerpApi dashboard where your API key is displayed immediately after signup.
- Copying the key — it is a single static token tied to your account plan. Free-tier accounts include a limited monthly search quota; paid plans unlock higher volumes.
The key must have access to the Google Flights engine (google_flights), which is included on all SerpApi plans by default.
Configure this secret in Arcade by following the Tool Secrets guide or add it directly at https://api.arcade.dev/dashboard/auth/secrets.

|---|---|---|---|
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 |
