Prompt Detail:
To get the CX value of your Google custom search engine, you need to follow a few simple steps. First, go to your Google custom search control panel at cse.google.com/cse/. Once you're there, navigate to the "Setup" menu and then click on "Basics" [1]. In this section, you will find the "Search Engine ID" field, which is the CX parameter used by the API to identify your custom search engine [2][3]. Simply copy the ID and use it as needed.
It's worth noting that the CX value is unique to each custom search engine you create, so you'll need to repeat these steps for each engine you want to use with the API. Additionally, you may also be interested in learning more about web crawlers and search engines in general [3].
