## Additional validation { #additional-validation }

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

### Import `Query` and `Annotated` { #import-query-and-annotated }

To achieve that, first import:

* `Query` from `fastapi`
* `Annotated` from `typing`

type objectHistogramInterval struct {
	name       string
	start, end int64
}

const (
	// dataUsageBucketLenV1 must be length of ObjectsHistogramIntervalsV1
	dataUsageBucketLenV1 = 7
	// dataUsageBucketLen must be length of ObjectsHistogramIntervals
	dataUsageBucketLen  = 11
	dataUsageVersionLen = 7
)

// ObjectsHistogramIntervalsV1 is the list of all intervals
