Service to check a URL for malware or phishing?

Question

Is there a service that lets me check a URL to see if it may possibly be a dangerous site?

When a user exits our application by clicking on an untrusted link, we sent them through a "are you sure you want to leave" redirection screen. It'd be a nice touch to do a quick check to see if we should warn the user as well.

Answer 1

Try with Google Safe Browsing API.

The Google Safe Browsing Lookup API is an experimental API that allows applications to check URLs against Google's constantly-updated lists of suspected phishing and malware pages.

Answer 2

You can use the Google Safe Browsing API to check if a URL is safe according to what they know about it. (API documentation)
