vowen watch streams new items as NDJSON, but it is poll based and needs a process sitting running to catch anything.
A webhook fired on completion would let an automation react to a finished meeting without holding a process open. A useful payload would be the item id, type, title, duration, and whether transcription succeeded.
Use case: when a client call finishes, a workflow picks up the transcript, drafts the follow up and files it, with no polling and nothing to babysit.
