Labs Intelix File Hash Lookup

https://api.labs.sophos.com/doc/lookup/files.html

Is there a test file that I can use that flags a score of < 30?

The test hashes work but if I hash an eicar file it doesn't flag it.. so I need a way to test the hashing process before I can drop it into the live environment.

I've tried the eicar files but they pass. So not sure if I am doing something stupid.
