Is it possible to extract a website safebrowsing info by javascript? This can be with Google Safe Browsing API, is there any code, or any article?
Related to your comment: This is not a code repository. You'll need to do your own development.
Back to your question: I would like to warn you that you will be exposing your API key to the general public when using javascript (as it's a client-side technology). Furthermore, you're opening the door to abusers. In the end, your "secret" API key might get suspended by Google quicker than you think.
In short: it could be done using the GET request examples the API documentation provides, but if I were you, I would think twice if javascript is really the best option you have.
