I would like to use http API to distinguish Raw from Hyper-text-markup-language.

You want to parse HTML? Good Luck!

If you just want to tell them apart and not parse it or anything try.
function isHTML(text)
local pattern = "<%s-!doctype%s+html%s->"
text = text:lower()
return text:find(pattern) ~= nil
end

That's a good idea, but many pages don't contain such a line. It would be safer to check the first two layers of actual HTML, I believe.
<html>.+<head>.+</head>.+<body>.+</body>.+</html>

I think we have two problems:
Some raw pages still contain HTML elements, just they don't get compiled
Some HTML pages have a license, for example:
[html]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">[/html]

For your second point
"<%s-!doctype%s+html.->"
For your first point I'm not exactly sure what you mean but a raw page should not start with <!doctype html>.

Because in a case like that it's impossible to tell if it's raw or HTML without prior context.

In fact, it would be easy to figure out if we had access to http headers and checking the Content-type field.Because in a case like that it's impossible to tell if it's raw or HTML without prior context.

Yes but sadly we do not. :/
