# Parámetros de Path y Validaciones Numéricas { #path-parameters-and-numeric-validations }

De la misma manera que puedes declarar más validaciones y metadatos para los parámetros de query con `Query`, puedes declarar el mismo tipo de validaciones y metadatos para los parámetros de path con `Path`.

## Importar Path { #import-path }

Primero, importa `Path` de `fastapi`, e importa `Annotated`:

# Pfad-Parameter und Validierung von Zahlen { #path-parameters-and-numeric-validations }

So wie Sie mit `Query` für Query-Parameter zusätzliche Validierungen und Metadaten deklarieren können, können Sie mit `Path` die gleichen Validierungen und Metadaten für Pfad-Parameter deklarieren.

## `Path` importieren { #import-path }

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`:
