Example response

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

That URL still says YOUR_ACCESS_KEY. A 7-day trial replaces it with a real key and returns the JFK departures that are late right now, in the JSON above. After the trial, Starter is $24.99/mo.
