Permanently delete a chat and every message in it. This cannot be
undone. Only chats owned by the key's organization can be deleted.

## Example request

```bash
curl -X DELETE "https://stylor.ai/api/v1/chat/YOUR_CHAT_ID" \
  -H "Authorization: Bearer $STYLOR_API_KEY"
```

## Path parameters

- `chatId` (string (uuid), required): The chat's id (a UUID). Surrounding whitespace is trimmed.

## Responses

### 200

The chat was deleted.

Content type `application/json`:

- `message` (string, required): Confirmation text.
- `chatId` (string (uuid), required): Id of the deleted chat (trimmed). [example `"3f0c2a4e-8b1d-4c6a-9e2f-7a5b1c0d9e88"`]

Example:

```json
{
  "message": "Chat deleted successfully.",
  "chatId": "3f0c2a4e-8b1d-4c6a-9e2f-7a5b1c0d9e88"
}
```

## Errors

Every error is a JSON object with an `error` string. Match on the status code; the message is written for people.

| Status | Message | When |
| --- | --- | --- |
| 404 | Chat not found or you do not have permission to delete it. | No chat with that id belongs to the organization. |
| 410 | This endpoint has been retired (v1/chat/[chatId]). | Always, for API callers. This check runs before authentication and consumes no quota. |
| 422 | A valid chatId is required. | The path segment is only whitespace (for example `%20`). |
