Google Flights Toolkit

Arcade's Google Flights toolkit gives LLMs access to real-time flight data via the SerpApi Google Flights endpoint, covering search, airport lookup, and booking-option resolution.

Capabilities

  • Flight search — one-way, round-trip (single call with both outbound and return dates), and multi-city/open-jaw itineraries; each result includes a direct google_flights_url for immediate handoff to the user
  • Pricing correctness — round-trip and multi-city fares are priced as bundles; the toolkit is designed around single bundled queries rather than summing separate one-way fares, which is typically more expensive and inaccurate
  • Airport/city lookup — resolve city names, country names, or airport names to IATA codes; metropolitan codes (NYC, LON, TYO, PAR) are accepted in searches to mean "any airport in this city"
  • Booking-option resolution — convert a booking_token from any search result into the full list of airlines and OTAs selling that specific itinerary, with optional POST data for backend vendor hand-off

Secrets

SERP_API_KEY — A SerpApi API key used to authenticate all requests to the Google Flights endpoint. To obtain one: create an account at SerpApi, then find your private API key on the dashboard. The free tier provides a limited number of monthly searches; paid plans are required for higher volume. No special scopes need to be selected — the key grants access to all SerpApi endpoints including Google Flights.

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.
