maybe not, i'm not sure now
in the index file in the api directory this is there
* File API for cross site deletes, uploads, etc.
*
* Requires a valid api key and username. Call in the format:
* http://yoursite.com/api/?key=[key]&username=[username]&action=[method]&file_id=123
*
* Output is json encoded result.
*
* Available methods. Note each may require additional parameters to be passed:
*
* list - Gets list of file ids and urls within account. No additional parameters required
* info - Gets details about a file within the logged in account. Requires file_id
* delete - Deletes a file. Requires file_id
* movefile - Moves a file from 1 server to another.
*/
so it looks like it might be just for moving files between file servers
