The request form will *never*[1] return json, because it returns before the
request is complete. This is what asynchronous means, and that is why I
said "The real job must be done by a callback function".
The very first example in the homepage of the package uses httpbin.org.
Here's a simplified version of it :
(request
"http://httpbin.org/get"
:parser 'json-read
:success (function*
(lambda (&key data &allow-other-keys)
(message "response: %S" data))))
Please try it and see what happens. The function mentionned as :success
takes over once the request is complete (well, unless the request fails
obviously...). That is a "callback" function.
HTH,

[1] Except in the synchronous case, e.g.
(request-response-data
(request "http://httpbin.org/get" :parser 'json-read :sync t))
But the doc explicitly says to not use that.
