How long will WordPress Support Jetpack JSON API

I was using the WordPress REST API V2 (https://blogurl.com/wp-json/wp/v2/posts) but it’s not returning the response the way I want it. However I stumbled on the Jetpack Json API (https://public-api.wordpress.com/rest/v1/sites/blogurl.com/posts) and it is returning the response the way need it.

But since I am using it for an iOS app I wanted to know how long it’ll last before WordPress pulls the plug on it.
