# Query Parametreleri ve String Doğrulamaları { #query-parameters-and-string-validations }

**FastAPI**, parametreleriniz için ek bilgi ve doğrulamalar (validation) tanımlamanıza izin verir.

Örnek olarak şu uygulamayı ele alalım:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

	}
	x.versions = x.versions[:versions]
	x.data = data
	x.metaV = metaV
	if err = x.data.validate(); err != nil {
		x.data.repair()
		storageLogIf(GlobalContext, fmt.Errorf("xlMetaV2.loadIndexed: data validation failed: %v. %d entries after repair", err, x.data.entries()))
	}
	return decodeVersions(buf, versions, func(i int, hdr, meta []byte) error {
		ver := &x.versions[i]
		_, err = ver.header.unmarshalV(headerV, hdr)
