how do i get my data from pocket back

Is there any way to get data back from pocket? I have been using it since it started to save articles for a book I'm working on. I have saved and sorted hundreds of articles. When mozilla acquired pocket I was so happy that it was taken over by a stable company. I had to take a year off from the project and I return to find this. I somehow missed the one email notifying me it was shutting down. My firefox search page to this day still gives me articles under a heading that reads "recommended by pocket" Is there any way to check if any of the info connected with my account still exists?
