If you are trying to get the share count of your posts with the facebook REST API endpoint
you get the error message
REST API is deprecated for versions v2.1 and higher.
The reason for this is that facebook switched the REST API endpoint into deprecated state on february 7th with an official announcement saying:
Version 2.0 will expire on August 7, 2016, two years after the release of v2.1.
The FQL and REST APIs are no longer available in v2.1: Previously announced with v2.0, apps must migrate to versioned Graph API calls starting with v2.1.
Today on August 19th 2016 facebook shut down the api completely and we do not get any results except the error message above.
So how to get shares of a url?
We can switch over to their graph api and their public available endpoint
This endpoint is returning the shares of your posts and its still public available but it is possible that this endpoint will be closed to the public in the future and only available via oAuth authentication.
Do you have more insights?
