Get the billing outcome for a specific training job, by job ID.

Reports whether the job was billed and, if so, the charge and compute
duration. The route uses the same access controls as other training-job
read endpoints.

## Path parameters

- `job_id` string, required

## Response `200`

Successful Response

- TrainingJobBillingResponse: Billing outcome for a training job.
  - `billed` boolean, required: Whether a billing record exists for this job; see charged_usd for the amount.
  - `billed_at` string, nullable: When the billing request row was created.
  - `charged_usd` string, nullable: Selling price actually charged for this job's GPU time.
  - `completed_at` string, nullable
  - `compute_started_at` string, nullable: When training compute began. Distinct from started_at. Failed or cancelled jobs are billed only when this is set, so null explains why billed is false.
  - `gpu_minutes` string, nullable: Billed GPU minutes, derived from the billed request's duration_ms.
  - `job_id` string, required
  - `request_id` string, nullable: Billing request identifier, when billed.
  - `started_at` string, nullable: When the job was dispatched to Modal (spawn / queue time).
