What is the Reverse Image Search API?
A Reverse Image Search API is a software interface that allows developers to programmatically search the internet (or a specific image database) using an image instead of text. The API takes an image file or image URL as input and returns data about visually or contextually similar images.
Using an external API in your application means you're using a service provided by another platform or server to extend your app's functionality, without building that functionality yourself. For example, if you're using a Reverse Image Search API, your app sends an image to the API and receives results like matching images, sources, or metadata in return.
