Example response

Field names match the live API. This flight only shows the shape. It is not a live result.

{ "success": true, "data": [ { "airline_iata": "AA", "flight_iata": "AA100", "flight_number": "100", "dep_iata": "IAD", "arr_iata": "DEN", "dep_time": "08:00", "days": [ "mon", "tue", "wed", "thu", "fri" ] } ] }

That URL still says YOUR_ACCESS_KEY. A 7-day trial replaces it with a real key and returns each IAD–DEN flight in the JSON above. After the trial, Starter is $24.99/mo.
