## Returning a custom `Response` { #returning-a-custom-response }

The example above shows all the parts you need, but it's not very useful yet, as you could have just returned the `item` directly, and **FastAPI** would put it in a `JSONResponse` for you, converting it to a `dict`, etc. All that by default.

Now, let's see how you could use that to return a custom response.

			// consider the offline disks as consistent.
			continue
		}
		if !meta.Deleted {
			if len(meta.Erasure.Distribution) != len(onlineDisks) {
				// Erasure distribution seems to have lesser
				// number of items than number of online disks.
				inconsistent++
				continue
			}
			if meta.Erasure.Distribution[i] != meta.Erasure.Index {
				// Mismatch indexes with distribution order
				inconsistent++
			}
		}

**FastAPI** は開発者の利便性のために `fastapi.responses` という `starlette.responses` と同じものを提供しています。しかし、利用可能なレスポンスのほとんどはStarletteから直接提供されます。

## カスタム `Response` を返す

上記の例では必要な部分を全て示していますが、あまり便利ではありません。`item` を直接返すことができるし、**FastAPI** はそれを `dict` に変換して `JSONResponse`　に含めてくれるなど。すべて、デフォルトの動作です。

では、これを使ってカスタムレスポンスをどう返すか見てみましょう。
