```JSON
{"item_id":3}
```

/// check

Notice that the value your function received (and returned) is `3`, as a Python `int`, not a string `"3"`.

So, with that type declaration, **FastAPI** gives you automatic request <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>.

///

## Data validation

  private val path = mutableListOf<String>()

  /**
   * False unless we made a recursive call to [write] at the current stack frame. The explicit box
   * adapter can clear this to synthesize non-constructed values that are embedded in octet strings.
   */
  var constructed = false

  fun write(
    name: String,
    tagClass: Int,
    tag: Long,
    block: (BufferedSink) -> Unit,
  ) {

```JSON
{"item_id":3}
```

/// check | Revisa

Observa que el valor que recibió (y devolvió) tu función es `3`, como un Python `int`, y no un string `"3"`.

Entonces, con esa declaración de tipos **FastAPI** te da <abbr title="convertir el string que viene de un HTTP request a datos de Python">"parsing"</abbr> automático del request.

## Validación de datos

	if err != nil {
		writeErrorResponseJSON(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

	buckets := make([]string, 0, len(bucketInfos))
	for _, bInfo := range bucketInfos {
		buckets = append(buckets, bInfo.Name)
	}

	var id string
	if id, err = pools.initRebalanceMeta(ctx, buckets); err != nil {
		writeErrorResponseJSON(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

func (client *storageRESTClient) ReadXL(ctx context.Context, volume string, path string, readData bool) (rf RawFileInfo, err error) {
	ctx, cancel := context.WithTimeout(ctx, globalDriveConfig.GetMaxTimeout())
	defer cancel()

	// Use websocket when not reading data.
	if !readData {
		resp, err := storageReadXLRPC.Call(ctx, client.gridConn, grid.NewMSSWith(map[string]string{
			storageRESTDiskID:   *client.diskID.Load(),

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

```Python hl_lines="1  8-10  13  18"
{!../../docs_src/path_operation_configuration/tutorial002b.py!}
```

## Summary and description

You can add a `summary` and `description`:

//// tab | Python 3.10+

///

Then, we can pass more parameters to `Query`. In this case, the `max_length` parameter that applies to strings:

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```
