How this service works
Read any public web page or PDF and get its main content as clean, LLM-ready markdown (headings, lists, links, tables, code) plus metadata: title, description, author, date, language, canonical URL. Menus, cookie banners and footers removed. Optional list of links. SSRF-safe fetching.
Output
Returns a JSON object with: the resolved URL, content type (html/pdf), word count, character count, a boolean indicating if content was trimmed, the markdown string of the main content, a metadata object (title, description, site, language, canonical URL, OG image), optional array of links found on the page, and any warnings (e.g. content was trimmed).
Example use cases
Feed documentation page to LLM
“Grab the content of https://platform.openai.com/docs/guides/function-calling and convert it to clean markdown so I can paste it into my prompt as context — limit it to 15000 characters.”
Extract article text from news URL
“Fetch this news article at https://www.bbc.com/news/technology-68594831 and return just the main article text as markdown, no menus or cookie banners, and also give me the title, author, and publication date from the metadata.”
Read a public PDF as markdown
“Can you read the PDF at https://arxiv.org/pdf/2303.08774 and give me its content as clean markdown, up to 50000 characters?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/web-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to give an LLM the content of a specific public URL — a docs page, article, or PDF — as clean, structured markdown without writing your own scraper. It is purpose-built for agentic workflows where boilerplate removal, metadata extraction, and LLM-readiness matter. Prefer it over generic HTTP fetch tools when you want headings, lists, links, tables, and code blocks preserved, and noise like cookie banners removed automatically. SSRF-safe fetching makes it suitable for untrusted or user-supplied URLs.
Side effects
- URL is unreachable or returns non-200 status — endpoint returns an error with the HTTP status from the origin
- URL points to a private/intranet address — blocked by SSRF-safe fetching policy
- Page requires JavaScript rendering — static fetcher may return empty or incomplete content
- PDF is scanned image-only — markdown output may be empty or minimal
- max_characters set below 500 or above 100000 — validation error returned
- URL is malformed or missing scheme — schema validation error on the url field
