URL Shortener API on Wordpress

Hi! Does anyone know how to implement Json API on a self-hosted wordpress site? No plugins found.
Would appreciate some resources. Get in touch if you are an experienced WP developer

Can you describe what it is that you’re trying to accomplish?

JSON is just a method of transferring data between the browser and the server using JavaScript.

jQuery has built-in methods for handling JSON, if that’s what you’re looking for.
