  get "/users/:id" do |req, res|
    user_id = req.params[:id]
    
    res.status_code = 200
    res.headers = { "Content-Type" => "application/json" }
    res.body = JSON.generate({
      id: user_id,
      name: "User #{user_id}",
      email: "user#{user_id}@example.com"
    })
    res
  end
  
  # POST - Create resource
  post "/users" do |req, res|
    data = JSON.parse(req.body)
    
    res.status_code = 201
    res.headers = { "Content-Type" => "application/json" }
    res.body = JSON.generate({
      id: rand(1000),
      name: data["name"],
      email: data["email"],
      created: true

    res

    res.headers = { "Content-Type" => "application/json" }
    res.body = JSON.generate({
