Wordpress REST API (wp-api) 404 Error: Cannot access the WordPress REST API

Question

I have been using the Wordpress REST plugin WP-API for months now while developing locally with XAMPP. I recently migrated my site to an EC2 instance and everything is working fine except I now get a 404 with the following message whenever I try to access any endpoint on the API:

The requested URL /wordpress/wp-json/ was not found on this server

Pretty permalinks are enabled with the following structure http://.../wordpress/sample-post/ which works fine when navigating to a specific post in the browser.

Here are some details about my setup:

• Wordpress 4.4.1
  • Not a Multisite
• WP REST API plugin 2.0-beta9
• Apache 2.2.22
• Ubuntu 12.04.5

Any help would be greatly appreciated as I have gone through SO and the WP Support forums for several hours and am out of ideas. Thank you!

UPDATED NEW WAY

I also faced similar problem in a local project. I used index.php after my project url and it worked.

http://localhost/myproject/index.php/wp-json/wp/v2/posts 

If it displays a 404 error then update permalinks first (see "Paged Navigation Doesn't Work" section

If it works, maybe you need to enable mod_rewrite, on ubuntu:

a2enmod rewrite sudo service apache2 restart 

Installation

The REST API is included in WordPress 4.7! Plugins are no longer required, just install the latest version of WordPress and you're ready to go.

If you're before 4.7:

1. Download plugin from here: http://v2.wp-api.org/

2. install and activate it.

Usage

To get all posts:

www.mysite.com/wp-json/wp/v2/posts 

For the search functionality, searching for test post looks like this:

/wp-json/wp/v2/posts?filter[s]=test 

Answer 2

I had this problem with the latest WordPress 4.7+. In my case the REST API only worked after I changed the permalinks setting to something other than "Plain", which was the default setting for my installation.
