 Googlesearch uses the Google search engine and [Google Dorks](https://en.wikipedia.org/wiki/Google_hacking) to search phone number's footprints everywhere on the web. It allows you to search for scam reports, social media profiles, documents and more. **This scanner does only one thing:** generating several Google search links from a given phone number. You then have to manually open them in your browser to see results. So the tool may generate links that do not return any result. This is a design choice we made to avoid technical limitation around [Google scraping](https://en.wikipedia.org/wiki/Search_engine_scraping).
 
-You can however, use this scanner through the REST API in addition with another tool to fetch the result automatically.

+## Googlecse
+
+Google custom search is a Google product allowing users to create Programmable Search Engines for programmatic usage.
+This scanner takes an existing search engine you created to perform search queries on a given phone number.
+
+Custom Search JSON API provides 100 search queries (~50 scans) per day for free. If you need more, you may sign up for billing in the API Console. **Additional requests cost $5 per 1000 queries (~500 scans), up to 10k queries per day (~5000 scans)**.
+
+Follow the steps below to create a new search engine : 
+
+1. Go to [GCP console](https://console.cloud.google.com/apis/api/customsearch.googleapis.com/metrics) and enable the custom search API.
+2. Go to the [credentials page](https://console.cloud.google.com/apis/credentials) and create a new API token. You can restrict this token to the Custom Search API.
+3. [Follow this link](https://programmablesearchengine.google.com/controlpanel/all) and click on "Add" to create a new search engine.
+4. Fill the form and make sure you select "Search the entire web".
+5. Use the Search Engine ID and the API token to configure the scanner as per the configuration tab below.

 OVH, besides being a web and cloud hosting company, is a telecom provider with several VoIP numbers in Europe. Thanks to their API-key free REST API, we are able to tell if a number is owned by OVH Telecom or not.
