Response

Success Response (200)

Returns a binary audio stream. The response is not JSON — it is the raw audio file.

HTTP/1.1 200 OK
content-type: audio/ogg
content-length: 1083518

string

Audio format — typically audio/ogg or audio/mpeg

integer

Size of the audio file in bytes

The response is a binary audio stream, not JSON. Use the -o flag with curl to save it to a file, or use the URL directly in an HTML <audio> tag for playback.

Not Found (404)

Returned when the recording has not been generated yet (e.g., call is still in progress or too short).
