# Get Messages

`GET /v1/omni-ai/threads/{thread_id}/messages`

List finalized messages in a thread.

Returns the latest page of **finalized** messages by default, with messages
within each page ordered chronologically. Messages from in-progress
assistant turns are excluded — use
`GET /omni-ai/threads/{thread_id}/response` or
`GET /omni-ai/responses/{response_id}` for live output.

If the last finalized message has role `USER`, an active response likely
exists and should be polled separately.

## Path parameters
