HTTP 204 Inspector

HTTP 204 No Content indicates the server has successfully fulfilled the request and there is no additional content to send in the response body. The response MUST NOT include a body. This status is the correct choice for successful DELETE operations, PUT/PATCH updates where the client doesn't need the updated resource back, and actions like 'mark as read' or 'toggle favorite' where the outcome is binary. The key distinction from 200 OK with an empty body is that 204 explicitly tells the client 'there is intentionally no content here.'
