# Additional Status Codes { #additional-status-codes }

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

/// note | Technical Details

The other two variables, `image_base64` and `binary_image`, are an image encoded in Base64, and then converted to bytes, to then pass it to `io.BytesIO`.

Only so that it can live in the same file for this example and you can copy it and run it as is. 🥚

///

If you don't declare a response model, FastAPI will use the `jsonable_encoder` explained in [JSON Compatible Encoder](../tutorial/encoder.md) and put it in a `JSONResponse`.
