You **don't call it** directly (don't add the parenthesis at the end), you just pass it as a parameter to `Depends()`.

And that function takes parameters in the same way that *path operation functions* do.

/// tip

You'll see what other "things", apart from functions, can be used as dependencies in the next chapter.

Você também poderia usar `from starlette import status`.

**FastAPI** fornece o mesmo `starlette.status` como `fastapi.status` apenas como uma conveniência para você, o desenvolvedor. Mas vem diretamente do Starlette.

## Tags { #tags }

Você pode adicionar tags para sua *operação de rota*, passe o parâmetro `tags` com uma `list` de `str` (comumente apenas um `str`):

  static class NonTerminalImmutableMapEntry<K, V> extends ImmutableMapEntry<K, V> {
    /*
     * Yes, we sometimes set nextInKeyBucket to null, even for this "non-terminal" entry. We don't
     * do that with a plain NonTerminalImmutableMapEntry, but we do it with the BiMap-specific
     * subclass below. That's because the Entry might be non-terminal in the key bucket but terminal
     * in the value bucket (or vice versa).
