Jetpack!

Sending requests to WP REST API of the Jetpack site

You can send requests to the WP REST API of any site that has Jetpack 4.5 or newer, and is connected to WordPress.com for the current user. Requests are sent to a special WordPress.com endpoint, which proxies the request, signs it and safely dispatches it to the remote site, returning the output from the remote endpoint.
