What is an API and why is API useful?

Posted by andreyass on September 27th, 2019

API means "Application Programming Interface". An Google serp api provides a set of commands, functions, and protocols to facilitate software programming. These predefined functions simplify the interaction of the programmer with the operating system since the hardware (monitor, data on the hard disk, etc.) does not have to be directly addressed. When it comes to the Internet, Web APIs are at the forefront and also serve as an interface to allow the use of existing third-party functions.

Web API 

Since the time of Web 2.0, the term serp api has been increasingly mentioned about the Internet. A web API is an interface for web pages and applications. It is used in the exchange and processing of content between websites and allows third parties to access data groups and user circles. The authorization API and the authentication API are two special types of web API.

Authorization API: Interface to give users access. Here the Authorization standard has been established. A user can independently agree that their data is accessible to third parties through APIs. An example is external applications that publish tweets in the user's name.

Authentication API: An interface to authenticate users. A user can be identified on a platform where he does not have a personal account. Instead, authentication is done in collaboration with an authorization API through a web page on which the user is connected. The best example is Facebook Connect.

Statement based on Google APIs 

Google's search engine provides many APIs as part of its services. Google Search API allows other websites to pass Google services directly to their visitors without the need to retrieve the Google website. An example is Google Maps. A restaurant can include a section of Google Maps on its website, indicating the location of the restaurant. This is possible because Google provides "Google Maps Image APIs". These Google searches api are the interface between the Google Maps service and any other website that uses the APIs.

Another simple example is the YouTube service and the YouTube API. It allows the integration of YouTube videos on any website. Webmasters can use the external service on their website and make it available to their visitors through the interface provided. Google offers Google webmaster tools API for search engine optimization. It allows webmasters who want to write their tools to access data such as keywords in search queries. Programmers can create applications themselves because they have access to the required data through the interface. Many of these APIs can be used for free, only a few are paid.

Why is API useful?

To reduce repetitive work: With such a wide variety of products and services available worldwide, it is not uncommon to see developers create something that is already invented. APIs can provide equipment with pre-configured tools and functions that save them having to create these tools from scratch.

To encourage innovation and collaboration: In some cases, APIs have been at the forefront of technological and scientific innovation. Currently, bing serp api such as Google Genomics allow researchers to easily analyze large amounts of genetic research, which helps them discover new treatments, as well as get more information about how genetic disorders develop.
