I noticed that http services that receive and return JSON are called 'Web Api/Web Service' in many articles/book/documentation etc.
But isn't the Web (World Wide Web) basically about websites, html and web browsers? To simply define, browsers retrieve HTML files from a server, renders and present them to end users.
So why are http services that receive and return JSON called 'Web Api/Web Service'? This service does not return HTML or it's response does not rendered by browsers. This API may not even be used by a website. For example, it may have been written only for another business microservice or mobile applications.
