Google Flights Toolkit

The Google Flights toolkit lets Arcade-powered agents search flights, resolve booking options, and look up airport codes by routing requests through the SerpApi Google Flights API.

Capabilities

  • Airport lookup: Resolve city names, country names, or airport names to IATA codes, including metropolitan codes (NYC, LON, etc.) accepted by flight searches.
  • One-way & round-trip search: Search for one-way or round-trip itineraries in a single call; results include direct google_flights_url links for immediate user hand-off without a separate booking step.
  • Multi-city (open-jaw) search: Query bundled multi-leg itineraries that are typically cheaper than summing equivalent one-way fares; never substitute multiple one-way calls.
  • Booking options resolution: Resolve a booking_token from search results to the airlines and OTAs selling that specific itinerary, with optional POST data for backend vendor hand-off flows.

Secrets

SERP_API_KEY — A SerpApi API key used to authenticate all requests to the Google Flights endpoint. Obtain it as follows:

  1. Create or log in to a SerpApi account.
  2. Navigate to your SerpApi dashboard and copy the API Key shown on the page.
  3. Free-tier accounts have a limited monthly search quota; production usage requires a paid plan that covers the expected request volume.

Store the key as a secret in Arcade. See Arcade secret configuration docs and the Arcade secrets dashboard.

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.

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 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.
