One stored posting, to learn whether it is still live (Reqbeat `GET /v1/jobs/role`). Takes the `company_id` and `req_key` a job search row carries. A live posting answers its role row; one that is closed, unknown or not fresh enough is a `not_found` miss, which is the answer "closed", not a failure. Billed per found role, never for the miss.
