### Anything else that can help to cover this?

_No response_

Start with the linked API documentation page and compare its POST /V1/customers endpoint with the store-view-prefixed endpoint described in the issue. Read the referenced Magento issue for context and verify the behavior against the stated Magento 2.4.5-P8 steps; done means the documentation accurately describes the working endpoint and expected response.
