                "id": {"type": "string"}, "name": {"type": "string"}
              }}

        }
      }
    }
  }
}

REVIEW
An API specification should reflect the actual contract, including errors and authentication. Mark unknown behavior instead of inventing a polished endpoint description.

This is a teaching example, not a live execution record.
