This idea is a bit of an addendum to Bob Gaydos' idea to create an endpoint that allows writing to review files (https://ideas.iii.com/forums/951745-ils-sierra/suggestions/50308716).

The current API cannot provide a list of empty files. That information would be incredibly helpful in conjunction with the other idea so that you may programmatically identify an available review file of sufficient size for your needs. Beyond that, it may be useful to use the API to write an alert mechanism for when your system may be running low on available files.

It is possible to explore this information via SQL, but the permissions are so much more granular with the APIs so there is an advantage to being able to set up an API key with access for these tasks that would not have access permissions for other more sensitive parts of the system.
