is a set of rules and protocols for building and interacting with software applications. It acts as an intermediary that allows two applications to communicate with each other.
Google does not offer a direct API for its image search. As a workaround, users can create Programmable Search Engines (formerly known as Custom Search Engines).
After creating a PSE, you will receive a unique Search Engine ID. This ID is used to specify which search engine to query.
To access and integrate your Programmable Search Engine with applications, you need a Google API Key. This key is obtained from the Google Cloud Console and is used to authenticate your requests to the Google Custom Search JSON API.
