The Custom Search JSON API helps programmers use programmable search engines in their web applications. It helps them retrieve and display outputs of the search engine using a JSON format.

Getting the Custom Search JSON API key

Here is how to get the Custom Search JSON API key:

  • To get our Custom Search JSON API key, we first need to open the link here.
  • Upon clicking the link, we see the following page:

  • Here, we need to scroll down to the “API key” section and click the button labeled “Get a Key.”
  • This brings up a popup where we need to first create a project. We can click the dropdown to see previous projects.
  • We click “Create a new project” to make our own project.

Note: We can give it any name we want.

  • Next, we click the “Yes” checkbox to agree to the terms and conditions.
  • Then, we click “Next” to get our API key.
  • After that, we get the following popup. We click on “SHOW KEY” to see our API key.
  • We can copy the key to our clipboard and use it to integrate our programmable search engine into your web application.

Note: The free version of Custom Search JSON API has a limit of 100 search queries per day. If we require more than this, we can pay $5 per 1000 queries for up to 10,000 queries a day. We can signup for billing using the API Console. If we want to search 10 or fewer specific websites with unlimited queries, we can check out the Custom Search Site Restricted JSON API.
