APIs to access the Google Safe Browsing lists of unsafe web resources.

What is Safe Browsing?

Safe Browsing is a Google service that lets client applications check URLs against Google's constantly updated lists of unsafe web resources. Examples of unsafe web resources are social engineering sites (phishing and deceptive sites) and sites that host malware or unwanted software. Come see what's possible.

With Safe Browsing you can:

  • Check pages against our Safe Browsing lists based on platform and threat types.
  • Warn users before they click links in your site that may lead to infected pages.
  • Prevent users from posting links to known infected pages from your site.

The Safe Browsing API is for non-commercial use only. If you need to use APIs to detect malicious URLs for commercial purposes - meaning 'for sale or revenue-generating purposes' - please refer to the Web Risk API.
