How to enable Safe Search in my Android browser

Requirement

I have requirement in my browser to enable/disable safe search while browsing.

On Google Safe Search Page

Block explicit results on Google using SafeSearch

You can filter explicit search results on Google, like pornography, with the SafeSearch setting. SafeSearch isn’t 100% accurate. But it can help you avoid explicit and inappropriate search results on your phone, tablet, or computer.

As you know when safe search is turned on (like google chrome), then user does not see results of many threat types, infected pages, social engineering pages, pornography etc. and block explicit images, videos, and websites from Google Search results

This is available on Google platforms like chrome, google app etc. So I got this task but can I enable it in my browser?

Resources Found

I got hints from safe search api, but I don't know if it is helpful for me, because if I use this, I can do two things,

• Either I need to call api every-time user open a website (Lookup api)
• Or I can download all url data. (Update api)

Problem

1. How can I filter Google search results in my WebView? Is there some way provided by search engines like www.google.com , www.bing.com etc.
2. If above is not possible, is only way to call safe browsing lookup api and perform blocking/ warning when malware, infection found?

Can any friend give me any hints, if it is possible?
