Coming back to the previous code example, **FastAPI** will:

* Validate that there is an `item_id` in the path for `GET` and `PUT` requests.
* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.

                doc.put(ID_FIELD, Integer.toString(mainSize - i - 1));
                doc.put("score", 1.0f / (i + 2));
                builder.addDocument(doc);
            }
            for (int i = 100; i < inSize + 100; i++) {
                Map<String, Object> doc = new HashMap<>();
                doc.put(ID_FIELD, Integer.toString(i));
                doc.put("score", 1.0f / (mainSize + i + 2));

        defaultSettings.put(DefaultKeys.INDEX, (settingsId + ".suggest").toLowerCase());

        defaultSettings.put(DefaultKeys.ROLE_FIELD_NAME, "role");
        defaultSettings.put(DefaultKeys.LANG_FIELD_NAME, "lang");
        defaultSettings.put(DefaultKeys.PARALLEL_PROCESSING, Boolean.FALSE);

Volviendo al ejemplo de código anterior, **FastAPI**:

* Validará que haya un `item_id` en el path para requests `GET` y `PUT`.
* Validará que el `item_id` sea del tipo `int` para requests `GET` y `PUT`.
    * Si no lo es, el cliente verá un error útil y claro.

    * Swagger UI.
    * ReDoc.

Terugkomend op het vorige code voorbeeld, **FastAPI** zal:

* Valideren dat er een `item_id` bestaat in het pad voor `GET` en `PUT` verzoeken.
* Valideren dat het `item_id` van het type `int` is voor `GET` en `PUT` verzoeken.
    * Wanneer dat niet het geval is, krijgt de cliënt een nuttige, duidelijke foutmelding.

    * Swagger UI.
    * ReDoc.

Voltando ao código do exemplo anterior, **FastAPI** irá:

* Validar que existe um `item_id` na rota para requisições `GET` e `PUT`.
* Validar que `item_id` é do tipo `int` para requisições `GET` e `PUT`.
    * Se não é validado, o cliente verá um útil, claro erro.
