    **Deprecated**: `ORJSONResponse` is deprecated. FastAPI now serializes data
    directly to JSON bytes via Pydantic when a return type or response model is

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,
    HTMLResponse,
    JSONResponse,
    ORJSONResponse,
    PlainTextResponse,
    RedirectResponse,
    Response,
    StreamingResponse,
    UJSONResponse,
)
```

    )
    return item
```

## Performance

Do not use `ORJSONResponse` or `UJSONResponse`, they are deprecated.

Instead, declare a return type or response model. Pydantic will handle the data serialization on the Rust side.
