We use the checkfiles function to check file status. The RapidShare API docs can be found here :
http://images.rapidshare.com/apidoc.txt
The relevant function is documented thusly :
sub=checkfiles
Description:
Gets status details about a list of given files. (files parameter limited to 3000 bytes.
filenames parameter limited to 30000 bytes.)
Parameters:
files=comma separated list of file ids
filenames=comma separated list of the respective filename. Example: files=50444381,50444382 filenames=test1.rar,test2.rar
Reply fields:
1:File ID
2:Filename
3:Size (in bytes. If size is 0, this file does not exist.)
4:Server ID
5:Status integer, which can have the following numeric values:
0=File not found
1=File OK
3=Server down
4=File marked as illegal
6:Short host (Use the short host to get the best download mirror: http://rs$serverid$shorthost.rapidshare.com/files/$fileid/$filename)
7:MD5 (hexadecimal)
Reply format: integer,string,integer,integer,integer,string,string
