Overview
Takes a short audio recording and returns what was said as text. The audio is sent as base64 and the gateway builds the upload for you, so no multipart handling is needed on the caller's side. Recordings must be brief and modest in size; longer material should be split and submitted in pieces. Billing counts the seconds of audio, measured from the recording itself when it carries a readable header and from the duration you declare otherwise.
The transcript, with the request id and the model that produced it.
