# Ek Status Code'ları { #additional-status-codes }

Varsayılan olarak **FastAPI**, response'ları bir `JSONResponse` kullanarak döndürür; *path operation*'ınızdan döndürdüğünüz içeriği bu `JSONResponse`'un içine yerleştirir.

Varsayılan status code'u veya *path operation* içinde sizin belirlediğiniz status code'u kullanır.

## Ek status code'ları { #additional-status-codes_1 }

No estamos agregando el prefijo `/items` ni los `tags=["items"]` a cada *path operation* porque los hemos añadido al `APIRouter`.

Pero aún podemos agregar _más_ `tags` que se aplicarán a una *path operation* específica, y también algunas `responses` extra específicas para esa *path operation*:

{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[30:31] title["app/routers/items.py"] *}

        this.result = result;
        this.artifacts = Collections.unmodifiableSet(artifacts);
    }

    @Override
    public Iterator<Artifact> iterator() {
        return artifacts.iterator();
    }

    @Override
    public int size() {
        return artifacts.size();
    }

    @Override
    public DependencyResolutionResult getResult() {
