Only transmissions on this facility’s available channels.

​
Updates

Each update’s data has the same fields as one entry of transcripts in List transcripts, without search_score.
  • Only transmissions on available channels that have a transcript are sent.
  • callsigns and the callsign and airline_id filters use the flights the transmission was attributed to when it was processed; a later correction does not send the transmission again.
  • Use received_at to order transcripts.
  • Use Get transcript audio for a transmission’s audio.

​
Billing

Subscribing is free. Each transcript sent is charged as one transcript, at $0.03. See Pricing and Billing.

​
Refusals

The subscription is refused when no parameter was given, or when a filter is invalid, such as an unknown airline_id, a facility that is not covered, an unavailable channel, or atc_channel_ids with none on facility_id.
