It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

///

/// info

In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md){.internal-link target=_blank}.

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

		zb0001Len--
		zb0001Mask |= 0x1
	}
	// variable map header, size zb0001Len
	o = append(o, 0x80|uint8(zb0001Len))
	if zb0001Len == 0 {
		return
	}
	if (zb0001Mask & 0x1) == 0 { // if not omitted
		// string "V2Obj"
		o = append(o, 0xa5, 0x56, 0x32, 0x4f, 0x62, 0x6a)
		if z.ObjectV2 == nil {
			o = msgp.AppendNil(o)
		} else {
			// map header, size 1
			// string "DDir"

		zb0001, err = dc.ReadUint()
		if err != nil {

			return
		}
		(*z) = BitrotAlgorithm(zb0001)
