No API key was recognised. On a payable endpoint, presenting NO credential returns 402 with a payment menu instead - so a 401 means a key was sent and rejected, not that one was missing. On the keyless routes, the reads GET /v1/listings/{id} and GET /v1/board and the want registration POST /v1/wants, a call with no credential is served, so a 401 there means a credential was sent and not recognised.
