### Return a Response Directly { #return-a-response-directly }

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md){.internal-link target=_blank}.

{* ../../docs_src/response_model/tutorial003_02.py hl[8,10:11] *}

This simple case is handled automatically by FastAPI because the return type annotation is the class (or a subclass of) `Response`.

	// validate if target credentials are ok
	exists, err := clnt.BucketExists(ctx, tgt.TargetBucket)
	if err != nil {
		switch minio.ToErrorResponse(err).Code {
		case "NoSuchBucket":
			return BucketRemoteTargetNotFound{Bucket: tgt.TargetBucket, Err: err}
		case "AccessDenied":
			return RemoteTargetConnectionErr{Bucket: tgt.TargetBucket, AccessKey: tgt.Credentials.AccessKey, Err: err}

## Caso de Uso

Empecemos con un ejemplo de **caso de uso** y luego veamos cómo resolverlo con esto.

Imaginemos que tienes algunos **modelos de machine learning** que quieres usar para manejar requests. 🤖
