Let's try to post the book, Hackers: Heroes of the Computer Revolution to the Concierge endpoint, /api/feeder. We need to have the Concierge server running in another terminal window:

    $ curl -X POST -d '{"title": "Hackers: Heroes of Computer Revolution", "url": "http://www.gutenberg.org/cache/epub/729/pg729.txt"}' http://localhost:8080/api/feeder | jq                                                                       
      % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                     Dload  Upload   Total   Spent    Left  Speed
    100   162  100    51  100   111     51    111  0:00:01 --:--:--  0:00:01 54000
    {
      "code": 200,
      "msg": "Request is being processed."
    }

Next, let's see what happens on the server:

    $ go run main.go
