Make sure to set a valid accept header. The documentation has examples, and for Ruby using 'rest_client' it looks like so:

require 'rubygems'
require 'rest_client'

headers  = {:accept => "application/json"}
response = RestClient.get "http://api.themoviedb.org/3/movie/550?api_key=###", headers
puts response

Cheers.

thank you for the response, now my output on the screen is [#19, "status_message"=>"Invalid accept header"}, @response=#, @headers={"access-control-allow-origin"=>["*"], "age"=>["0"], "cache-control"=>["public, max-age=172800"], "content-type"=>["application/json;charset=utf-8"], "date"=>["Sat, 22 Dec 2012 22:39:37 GMT"], "etag"=>["\"32ce7fc39a8c593ec2e1e01f5f00527c\""], "server"=>["nginx"], "status"=>["406 Not Acceptable"], "via"=>["1.1 varnish"], "x-cache"=>["MISS"], "x-memc"=>["HIT"], "x-memc-age"=>["94192"], "x-memc-expires"=>["78608"], "x-memc-key"=>["my_key"], "x-varnish"=>["1173684056"], "x-varnish-sid"=>["tm-v-p-1100"], "x-xss-protection"=>["1; mode=block"], "content-length"=>["59"], "connection"=>["Close"]}>, {:accept=>"application/json"}]

Its ok all solved now, thanks. I wasnt setting the headers correctly, HTTparty have a slightly different way of doing it
