You can use the Google and Bing search APIs to develop software that can retrieve results programmatically from these major search engines. This API allows you to use a query to perform web searches or image searches.
The Google Custom Search API is required by the Google API Console. It is now easier to know about the best new azure and Microsoft 365 certification paths from Directions Training.

The API offers 100 searches per day for free. More returns means you'll have to pay for them ($ 5 per 1,000 requests, up to 10,000 requests per day). Starting August 1, 2012, Microsoft will charge for access to the Bing Search API (previously free) via the Windows Azure Marketplace.
With less than 5,000 requests per month, users can access the API for free. This should cover most nonprofits, educational institutions, and smaller applications. For more than 5,000 requests per month, you can purchase a subscription to Windows Azure Marketplace. If you are only interested in web results, we offer a lower price.
Paid services also require some developer integrations to accommodate some API changes. There are many resources on the web explaining how to migrate to a new platform for PHP, .net, Java, Delphi, and Python programmers.
When released, the Bing API was completely free, while Google always charged a fee for getting search results. The two services treat their free perks differently, so direct comparisons aren't easy, but Bing seems to be cheaper in most circumstances.
