## Embed a single body parameter { #embed-a-single-body-parameter }

Let's say you only have a single `item` body parameter from a Pydantic model `Item`.

By default, **FastAPI** will then expect its body directly.

But if you want it to expect a JSON with a key `item` and inside of it the model contents, as it does when you declare extra body parameters, you can use the special `Body` parameter `embed`:

```Python

        // The error should occur when System.arraycopy is called.
        ByteEncodable encodable = new ByteEncodable(data, 1, 2); // off=1, len=2, data.length=2. 1+2 > 2

        byte[] dest = new byte[5];

        // Expect IndexOutOfBoundsException from System.arraycopy
        assertThrows(IndexOutOfBoundsException.class, () -> {
            encodable.encode(dest, 0);
