About Web Search APIs

Websites have loads of data, which is not all the information relevant to our search. Therefore, there is a need to pinpoint information to save time and gather what we need from a particular website. API searches are designed and to perform this exact purpose.

API (Application Programming Interface) is a group of software that provides a set of functions to users where the underlying mechanism of that function is hidden. Web search APIs allow developers to add search capabilities into their websites and applications to return the information that is most relevant to the user query.

How web search APIs work

The first step is to find a search engine API that supports the coding language an individual is comfortable with. Most free web search APIs allow the use of different programming languages, and hence it is easy to identify a preferred API search engine.

The next step is to request an API key. An API key is what identifies a user and authenticate every action performed by the API. In other words, the API key sends signals to the API that grants access and initiate the user request.

After getting your API key, building your request and responses follows. Ordinarily, one can parse data through an HTTP protocol. A developer must clearly define the endpoints that make calls to the server to create, post, update, retrieve, or delete data.

The server returns a status code associated with the API search request. A 200 status code allows the client to know that the request went as expected. However, it is possible to get other status codes. The 400 range status codes indicate that something has gone wrong in the request. The 500 range show that something went wrong from the server-side.

Responses to the calls are returned in a given format. Extensible Markup Language (XML) and JavaScript object notation (JSON) is the most popular data interchange formats.
