# Parâmetros de consulta e validações de texto

O **FastAPI** permite que você declare informações adicionais e validações aos seus parâmetros.

Vamos utilizar essa aplicação como exemplo:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial001.py!}
```

   * AtomicInteger results in zero, we compareAndSet the value to zero; if that succeeds, we remove
   * the entry from the Map. If another operation sees a zero in the map, it knows that the entry is
   * about to be removed, so this operation may remove it (often by replacing it with a new
   * AtomicInteger).
