### Confira a documentação

Agora você pode iniciar a sua aplicação e ir até <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

Você verá que a sua documentação possui as *operações de rota* normais e agora também possui alguns **webhooks**:

      } catch (ClassCastException e) {
        return false;
      }
    }

    @Override
    int indexOf(@CheckForNull Object target) {
      if (contains(target)) {
        @SuppressWarnings("unchecked") // if it's contained, it's definitely a C
        C c = (C) requireNonNull(target);
        long total = 0;
        for (Range<C> range : ranges) {
          if (range.contains(c)) {

## OpenAPIとAPIドキュメント

ステータスコードとレスポンスを直接返す場合、それらはOpenAPIスキーマ (APIドキュメント) には含まれません。なぜなら、FastAPIは何が返されるのか事前に知ることができないからです。
