O *endpoint* que batemos traz uma lista de Quadrinhos. Essa foi a resposta que obtemos: ```elixir {:ok, %Tesla.Env{ method: :get, url: "https://gateway.marvel.com/v1/public/comics?apikey=d3f934e3c9ccb6de467674e4fc7a3ead&ts=1&hash=1d49870a0631827587878fcff98fa267", query: [], headers: [ {"connection", "keep-alive"}, {"date", "Wed, 08 May 2024 18:21:51 GMT"}, {"etag", "60ddd4a67c6e3242fa2560dbb0035b3925d666ef"}, {"content-length", "66553"}, {"content-type", "application/json;

Vamos fazer isso. {% code title="lib/coffee\_shop/integrations/marvel\_comics/response.ex" lineNumbers="true" %} ```elixir defmodule CoffeeShop.Integrations.MarvelComics.Response do defstruct status: :integer, body: :map def build({:ok, %Tesla.Env{status: status, body: body}}) do response = %__MODULE__{ status: status, body: body } {:ok, response} end end ``` {% endcode %} Ele segue a mesma estrutura do respose do Café. Deixo separado para facilitar tratamentos de resposta para cada integração. Não faz sentido termos a mesma resposta em várias integrações e logo veremos isso. Vamos adicionar em nosso cliente. 
defmodule CoffeeShop.Integrations.MarvelComics.Client do
  alias CoffeeShop.Integrations.MarvelComics.Response
  
  def comics(opts \\ []) do
    base_url = Keyword.get(opts, :base_url, base_url())

    opts
    |> new_client()
    |> Tesla.get("#{base_url}/v1/public/comics")
    |> Response.build()
  end

  defp new_client(_opts) do
    middlewares = [
      {Tesla.Middleware.Query, [apiKey: "12345", hash: "7EE341DFFE88E697114117AA51E1A210", ts: 1]}
    ]

    Tesla.client(middlewares)
  end

  defp base_url() do
    "https://gateway.marvel.com"
  end
end
Precisamos atualizar nosso teste 
defmodule CoffeeShop.Integrations.MarvelComics.ClientTest do
  use ExUnit.Case

  describe "comics/0" do
    test "respond a list of comics", %{bypass: bypass} do
      # ...
      
      assert {:ok, %Response{status: 200, body: _}} = Client.comics(opts)
    end

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://consumindo-apis-com-elixir.cafecomelixir.com.br/compondo-integracoes/marvel-api/lidando-com-a-resposta.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
