Introduction

To perform a search on Google using the REST APIs, we need to create a Custom Search Engine (referred from now on as CSE). We also need to enable Custom Search API for the account using which we are going to create CSE.

Google Search Service on Intelligence Platform needs 2 IDs to execute the search operation, CSE ID and Custom Search API Key. The free version of CSE only allows upto 100 searches/day using a single ID/Key pair. After that, the ID/Key Pair expires and is reset the next day.

IMPORTANT: Please make sure your Google Search instance must be accessible from the Klera Machine.

API Rate Limit: 10000 requests per day
