In wordcamp.org, we can use WP REST API.
So, I try to get some information.

Getting Sponsers Information

use query “wcb_sponsor”.
But you can not use ?filter[XXX]= & ?type=wcb_sponsor.

Example: Get Sponser Information on WordCamp US 2015

$curl -l https://2015.us.wordcamp.org/wp-json/posts?type=wcb_sponsor
[js]
$ curl -l https://2015.us.wordcamp.org/wp-json/posts?type=wcb_sponsor | jq ".[0]"

Using for Development Enviroment

If you want to use on WordPress Meta Environment

You should install WP API plugin yourself.

Warning:Check Version.

WordCamp.org using WP API v1.
you should install “WP REST API (WP API)”, NOT “WordPress REST API (Version 2)”.

Using WP-CLI

[bash]
$ vagrant ssh
$ cd /vagrant/www/wordpress-meta-environment/wordcamp.dev/public_html/wordpress
$ wp plugin install json-rest-api –activate
[/bash]
