Code Highlight Html API

POST https://api.findutils.com/api/tools/code-highlight-html/execute

Returns syntax-highlighted HTML for a code snippet: HTML-escaped text wrapped in <span style="color: ..."> elements using one of six colour themes (dracula, monokai, github, nord, one-dark, solarized). This is the pure highlighting step of the Code Screenshot Generator page; it returns markup plus the theme background and foreground colours, not an image.
