# Stream assistant reply (SSE)

GET https://astropods.com/api/v1/deployments/{deploymentId}/messaging/conversations/{conversationId}/stream

Server-Sent Events stream of the assistant's reply for the current turn.
Emits a `connected` event, incremental content chunks, and a terminal
`finish` (or `error`) event. Agent-produced file metadata appears in
`attachments` on the terminal chunk. Subscribe after sending a message.
Ownership-scoped: a conversation owned by another user returns 404.
