BEARER_TOKEN = "QYxS....laRik"
CUSTOM_DOMAIN = "localhost:8080"

require "uri"
require "json"
require "net/http"

url = URI("http://#{CUSTOM_DOMAIN}/v2beta/projects/search")

http = Net::HTTP.new(url.host, url.port);
request = Net::HTTP::Post.new(url)
request["Content-Type"] = "application/json"
request["Accept"] = "application/json"
request["Authorization"] = "Bearer #{BEARER_TOKEN}"
request.body = JSON.dump({})
