Se você não declarar um modelo de resposta, o FastAPI usará o `jsonable_encoder` explicado em [Codificador Compatível com JSON](../tutorial/encoder.md) e o colocará em uma `JSONResponse`.

Você também pode criar uma `JSONResponse` diretamente e retorná-la.

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

 * <p>
 * Parse the Java source file containing the versions declarations and use the known rules to figure out which are all
 * the version the current one is wire and index compatible with.
 * On top of this, figure out which of these are unreleased and provide the branch they can be built from.
 * <p>
 * Note that in this context, currentVersion is the unreleased version this build operates on.

Si declaras un [Response Model](../tutorial/response-model.md) FastAPI lo usará para serializar los datos a JSON, usando Pydantic.

Si no declaras un response model, FastAPI usará el `jsonable_encoder` explicado en [JSON Compatible Encoder](../tutorial/encoder.md) y lo pondrá en un `JSONResponse`.

También podrías crear un `JSONResponse` directamente y devolverlo.
