Hi Didier, cool project. I’ve developed something similar, but as a Java API – https://code.google.com/p/virus-total/

@gabriel Can you check with this new version: http://didierstevens.com/files/software/virustotal-search_V0_1_1.zip

No I have the same result. Maybe I request a lot of hash ? And VT blacklist me. I m gonna try with another IP and another key

@gabriel If you exceeded your VT quota, you get a 402 reply. The new version you tested handles 402 replies properly now.
So since you didn’t see a 402 reply in the report, there must be something else. Testing with another key might give you an indication.
