How does this differ from the Algolia HN API in terms of data access? (https://hn.algolia.com/api) I was able to download all HN data recently with ease using that endpoint. Authentication?
EDIT: After looking at the documentation there are two new aspects of the Firebase API not in the Algolia API:
1) Ability to see deleted/dead stories.
2) Endpoint for user data.
Question to kogir/dang: Has the "delay" field (Delay in minutes between a comment's creation and its visibility to other users) always been there?
