DELETE /api/v1/numbers/{id} only releases test numbers, with a test key. Releasing a live number cancels it at the carrier and stops its monthly fee, and the number is gone for good, so that is not possible through the API. Ask Hypamoon support at hello@hypamoon.com. The number stays in your project until then.
