### Add some custom `tags`, `responses`, and `dependencies` { #add-some-custom-tags-responses-and-dependencies }

We are not adding the prefix `/items` nor the `tags=["items"]` to each *path operation* because we added them to the `APIRouter`.

But we can still add _more_ `tags` that will be applied to a specific *path operation*, and also some extra `responses` specific to that *path operation*:

            assertThat(chain.request().body).isNull()
            val response = chain.proceed(chain.request())
            assertThat(response.header("Connection")).isEqualTo("Upgrade")
            assertThat(response.body).isInstanceOf<UnreadableResponseBody>()
            interceptedCount.incrementAndGet()
            response
          },
        ).build()
    webServer.enqueue(
      MockResponse

                final NameServicePacket response = this.responseTable.get(Integer.valueOf(nameTrnId));
                if (response == null || response.received) {
                    continue;
                }
                synchronized (response) {
                    response.readWireFormat(this.rcv_buf, 0);
                    response.received = true;

                    if (log.isTraceEnabled()) {

# Usando Dataclasses

FastAPI está construido sobre **Pydantic**, y te he estado mostrando cómo usar modelos de Pydantic para declarar requests y responses.

Pero FastAPI también soporta el uso de <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> de la misma manera:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

	apiErr, ok := e[errCode]
	if !ok {
		return e[ErrSTSInternalError]
	}
	return apiErr
}

// error code to STSError structure, these fields carry respective
// descriptions for all the error responses.
var stsErrCodes = stsErrorCodeMap{
	ErrSTSAccessDenied: {
		Code:           "AccessDenied",
		Description:    "Generating temporary credentials not allowed for this request.",
		HTTPStatusCode: http.StatusForbidden,

Il inclut les `tags`, `parameters`, `requestBody`, `responses`, etc.

Ce schéma OpenAPI spécifique aux *operations* est normalement généré automatiquement par **FastAPI**, mais vous pouvez également l'étendre.

/// tip | Astuce

Si vous avez seulement besoin de déclarer des réponses supplémentaires, un moyen plus pratique de le faire est d'utiliser les [réponses supplémentaires dans OpenAPI](additional-responses.md){.internal-link target=_blank}.

///

		if rec.Code != testCase.expectedRespStatus {
			t.Errorf("Test %d: %s: Expected the response status to be `%d`, but instead found `%d`", i+1, instanceType, testCase.expectedRespStatus, rec.Code)
		}

		// Verify response the V2 signed HTTP request.
		// initialize HTTP NewRecorder, this records any mutations to response writer inside the handler.
		recV2 := httptest.NewRecorder()
