Html Formatter

Validation REST API MCP

Format (beautify) or minify HTML and return the result with a tag-balance validation report. Format mode re-indents block tags, keeps inline tags with their text, and leaves pre/code/script/style/textarea content untouched. Minify mode strips comments and whitespace between tags.
