# Retrieve WoT Thing Directory headers

`HEAD /.well-known/wot`

Returns headers for the WoT Thing Directory endpoint without a response body.
Supports the same authentication and configuration as the GET method.

Authentication (security requirement alternatives):

```json
[
  {
    "OpenIDConnect": []
  },
  {
    "NginxBasic": []
  },
  {
    "Bearer": []
  }
]
```

- OpenIDConnect: openIdConnect. OpenID Connect Discovery URL. The placeholder is replaced by Swagger UI when configured.
- NginxBasic: http (basic). Eclipse Ditto sandbox demo user (demo1 ... demo9) + password (demo)
- Bearer: http (bearer). A JSON Web Token issued by a supported OAuth 2.0 Identity Provider.

Responses:

- 200: The WoT Thing Directory headers were successfully retrieved.

- 401: The request could not be completed due to missing authentication (when authentication is required).
