Job post locations are the join rows that attach one or more locations to a job_post — a multi-location posting (e.g. San Francisco, Remote (US), New York on a single role) has one row per location. GET /v3/job_posts does not return locations inline; pair this endpoint with it on job_post_id to assemble the candidate-facing location list. Filter with parent=job_post&ids=<job_post_id> to fetch every location on a specific post, or with parent=office / parent=custom_location to find every post in a given location.
