title: Are there any sample API without CORS?
body: <p>Currently i need a sample API to test AjaxDataSource on my Bokeh project( checked all API from this one <a href="https://github.com/toddmotto/public-apis" rel="nofollow noreferrer">https://github.com/toddmotto/public-apis</a>)</p>
  
  <p>But all of them require Cross-Origin Resource Sharing (CORS)</p>
  
  <pre><code>from datetime import date
  from random import randint
  from bokeh.models import AjaxDataSource, CustomJS
  from bokeh.models.widgets import DataTable, DateFormatter, TableColumn
  from bokeh.models.layouts import WidgetBox
  from bokeh.plotting import show, figure
  import numpy as np
  from flask import Flask, jsonify, make_response, request
  
  from bokeh.plotting import figure, show
  from bokeh.models import AjaxDataSource, CustomJS
  
  adapter1 = CustomJS(code="""
      const result = {x: [], y: []}
      const json = cb_data.response
      console.log("Hi")
      for (var key in json) {
         if (json.hasOwnProperty(key)) {
            result.x.push(json[key].nome);
            result.y.push(json[key].codigo);
         }
      }
      console.log(result)
      return result
  """)
  
  source = AjaxDataSource(data_url='https://parallelum.com.br/fipe/api/v1/carros/marcas', adapter = adapter1)
  
  columns = [
          TableColumn(field="x", title="Nome"),
          TableColumn(field="y", title="Codigo"),
      ]
  data_table = DataTable(source=source, columns=columns, width=400, height=280)
  
  show(data_table)
  </code></pre>
  
  <p>So i have this problem </p>
  
  <p><a href="https://i.stack.imgur.com/ZOaTA.png" rel="nofollow noreferrer">failed</a></p>
  
  <p>Are there any sample API that doesn't not require CORS out there? </p>
  
  <p>Thanks</p>
