# Get Build Events

`GET /api/v1/build/{job_id}/events`

Get events for a specific build job.

Requires authentication and ownership verification. A job owner is registered
when build_flow is called; if a registered owner does not match the requesting
user the endpoint returns 404 to avoid leaking job existence.
Jobs started via build_public_tmp have no registered owner and remain accessible
to any authenticated user.
