Finally found a screenshot API that handles full-page captures correctly. Most others mess up the rendering of dynamic elements. Geekflare API captures the whole thing.

If you are a developer building RAG pipelines, you need this. The URL to Markdown feature is much cheaper than the other big players in this space. It handles dynamic JS-heavy sites surprisingly well.
