Question

I’m just getting started with the Google Safe Browsing API to verify destination URLs for my URL shortening service http://lin.cr. Do I have to download the entire list of suspicious sites or is there a way I can run a check only when I need it?

I don’t have a crazy amount of traffic on the site, so I think it’s easier to do it live.

Answer 1

I am not sure that doing any kind of “live” stuff would be OK, considering the Acceptable Usage in Clients part of the documentation (quoting a few sentences) :

The second update request should
happen between 15-30 minutes later.
After that, each update should occur
once every 25-30 minutes.

And the paragraph after that one is pretty interesting, too :

To help maintain a high quality of
service, it may be necessary for the
update server to ask the client to
make less frequent requests.

Considering these, I would not do any king of “live” request : I’m afraid google wouldn’t quite like it…
