API with airport flight schedule?

Question

API

I tried using the Yandex.schedule API, but I didn't find it in the json about delayed flights.
I tried to get data through flightstats, but it gives an error related to authorization.
In general, the point is to send a request and get all the flights of the airport of a particular day, where information about the flight delay will be stored.
