Questions and answers

Why convert web pages to Markdown for LLMs?
Markdown keeps the structure models need while dropping markup, which usually cuts the token count substantially.
Why does Fetch URL fail on some sites?
The browser can only fetch pages that allow cross-origin requests. If a fetch fails, paste the HTML instead.

Use it as an API

Web-to-Markdown Converter is also callable as a free HTTP JSON API at https://aidevhub.io/api/web-to-markdown/ — GET with query parameters or POST with a JSON body, no authentication, CORS enabled, fair use (abusive traffic is throttled at the edge; there is no per-request quota header).
