# Stream Call Transcript

GET https://api.agentphone.ai/v1/calls/{call_id}/transcript/stream

Stream a call's transcript via Server-Sent Events.

On connect the server replays all existing transcript turns from the
database, then streams new turns in real time as they arrive from the
voice provider.  A ``: heartbeat`` comment is sent every 15 s to keep
proxies alive.  The stream closes after sending an ``ended`` event
when the call completes (or immediately after replay if the call has
already ended).

Works for both live and completed calls — same URL either way.
