How to access WP REST API for WordPress.com sites?

问题

I see WordPress.com recently started using Gutenberg, which relies on the WP REST API. I'm building a plugin and I'd like to use the WP REST API from a self-hosted site, and have it communicate with a WordPress.com site, but I'm having trouble finding the REST API base URL. For example, https://cmljnelson.wordpress.com/wp-json is a 404. The documentation about REST API discovery doesn't seem to apply to WordPress.com. How can I find the WP REST API base URL for WordPress.com sites?

回答1:

WordPress.com's REST API apparently is shared among sites hosted there and you can access it here: https://public-api.wordpress.com/wp/v2/.

If you want access to the REST routes of a specific site in WordPress.com, use the /sites route:

https://public-api.wordpress.com/wp/v2/sites/{site-id or domain}/
