Isso significa que o **FastAPI** vai esperar um corpo similar à:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Novamente, apenas fazendo essa declaração, com o **FastAPI**, você ganha:

	queueLength := len(h.logCh)
	h.logChMu.RUnlock()
	stats := types.TargetStats{
		TotalMessages:  atomic.LoadInt64(&h.totalMessages),
		FailedMessages: atomic.LoadInt64(&h.failedMessages),

	defer configLk.Unlock()

	defer configLk.RUnlock()

	return getMaxTimeout(c.MaxTimeout)
}

// LookupConfig - lookup config and override with valid environment settings if any.
