Use this when you want to know which AI crawlers a website bans. The Bouncer reads the domain robots.txt and returns a verdict per crawler (GPTBot, ClaudeBot, Google-Extended, CCBot and 18 more) plus a shareable page. Fetches one public file, cached a day. Read only.
```

### `menu`

```

### `pour`

```
