For those cases, you can use the `jsonable_encoder` to convert your data before passing it to a response:

{* ../../docs_src/response_directly/tutorial001.py hl[6:7,21:22] *}

/// note | Technical Details

You could also use `from starlette.responses import JSONResponse`.

If for some reason you need to disable this automatic conversion, you can do it as well for Pydantic models for header parameters.

/// warning

Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.
