Google Flights Toolkit

The Google Flights toolkit lets Arcade-powered agents search flights, resolve booking options, and look up airport codes via the SerpApi Google Flights API — no user authentication required.

Capabilities

  • Airport lookup: Resolve city names, country names, or airport names to IATA codes, including metropolitan codes (e.g. NYC, LON) that match any airport in a metro area.
  • One-way & round-trip search: Search for itineraries with flexible cabin class and passenger counts; round-trip searches are issued as a single call (not two one-ways) to get accurate bundled pricing. Results include direct google_flights_url booking links.
  • Multi-city (open-jaw) search: Search multi-leg itineraries that cannot be expressed as a simple one-way or round-trip; the bundled fare is typically cheaper than equivalent summed one-ways. Results also include direct google_flights_url links.
  • Booking option resolution: Convert a booking_token from any search result into the list of airlines and OTAs selling that specific itinerary, with optional POST data for backend vendor hand-off.

Secrets

SERP_API_KEY — An API key issued by SerpApi. SerpApi is the underlying data provider for Google Flights results. To obtain a key: create an account at serpapi.com, navigate to your dashboard, and copy the API key shown under Your Private API Key. Free-tier accounts have a monthly search limit; paid plans are required for higher volume. The key authenticates every flight search, airport lookup, and booking-options request made through this toolkit.

Resolve a ``booking_token`` to the airlines and OTAs selling that itinerary. Pass a ``booking_token`` from a one-way, round-trip, or multi-city flight search result 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.

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".
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.

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 several one-way searches 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.
