What are SEO APIs?

An SEO Application programming interface (API) is a code that allows users to retrieve data about their keyword rankings, backlink analysis, or general website performance metrics. 

Think of it as your personal assistant for your SEO projects. Instead of spending endless hours rummaging through reports, examining rankings, or extracting rankings, you simply request your assistant for certain information, which they deliver instantly. 

SEO APIs work in the same manner. They join your software to SEO databases, extracting SEO real-time data with just a button request. SEO APIs use the GET method to retrieve the SEO data and the POST method to display the response in a structured format like JSON.

Here’s an example of a JSON GET request for retrieving keyword ranking data from an SEO API.
