About this API

Google Safe Browsing provides a service to identify unsafe websites and links by flagging domains and URLs that may contain malware or phishing content. Developers can use this API to protect users by checking links before they are accessed or displayed.

This API is relevant for applications that require security checks on web content, such as browsers, email clients, or any software that processes URLs. It helps reduce exposure to malicious sites by leveraging Google's extensive threat intelligence.

Authentication is handled via an API key, making it straightforward to integrate into existing systems. The API primarily supports RESTful requests for querying the safety status of links and domains.
