JavaScript

There is a yandex schedule api that says:

https://api.rasp.yandex.net/v3.0/schedule/ ?apikey=<key>& station=<station code>

Actually airport codes according to ICAO IATA standards, even they have it written.
For example, a request for Domodedovo Airport - aka DME

https://api.rasp.yandex.net/v3.0/schedule/ ?
  apikey=<ключ>
& station=DME</blockquote>

In response: not the correct station code.
Tell me please.
