No new protocol or standard is needed for what you're describing. HTML is designed to do all of this by allowing a very fancy CSS and JavaScript for modern browsers but also be backwards compatible so you can literally use links. Unfortunately, I think that most web developers don't realize this is even a possibility anymore because if you're 35 or younger you never experienced what the web used to be unless you stumbled across some ancient site. You also have to think about the effort it takes to continue to remain compatible with a text only system. How many additional hours of development time and testing time does it take for the use case that you're describing and how many people would use that use case? The reason no one uses the functionality that already exists for sites to continue to present data when there is no CSS or JavaScript it's because almost no one browses that way and those places aren't interested in having customers that aren't using CSS or JavaScript. Generally what you want in a case like this is an API to interact with the site you're looking for data on. Most places that do have some sort of consumable data that would be useful in a programmatic mode have an API available to you.
