Wenn der Client beispielsweise versucht, einen `tool` Query-Parameter mit dem Wert `plumbus` zu senden, wie:

```http
https://example.com/items/?limit=10&tool=plumbus
```

erhält er eine **Error-Response**, die ihm mitteilt, dass der Query-Parameter `tool` nicht erlaubt ist:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
- Each pool expects each host in this pool has the same number of drives specified as any other host.
