How this service works
URL to clean, LLM-ready Markdown or JSON. Strips scripts, nav, and boilerplate; keeps headings, lists, tables, and code blocks. JSON mode adds the page title; every response carries a fetch timestamp. No signup, no API key — pay per call.
Output
Returns a JSON object containing the original URL, the chosen format ('markdown' or 'json'), the cleaned page content as a string with headings/lists/tables/code blocks preserved, and a fetched_at ISO 8601 timestamp indicating when the page was retrieved.
Example use cases
LLM context from live webpage
“Grab https://docs.openai.com/api-reference/chat and convert it to clean markdown so I can feed it to my model as context.”
Research article extraction
“Pull the content from https://www.nature.com/articles/d41586-024-00001-0 and return it as clean JSON — just the text, no nav or ads.”
Competitive pricing page scrape
“Fetch https://www.competitor.com/pricing and extract the main content as markdown so I can see their pricing tiers without all the page clutter.”
Technical details
Endpoint
POSThttps://api.nightcobbler.com/v1/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need clean, LLM-ready text from a URL without setting up an API key or signing up for a service. It is ideal for one-off or low-volume page extractions where you want structured Markdown or JSON output with boilerplate stripped. Prefer it over full browser automation tools when the page content is mostly server-rendered. It is pay-per-call via x402 protocol, making it cost-effective for sporadic use without subscription overhead.
Side effects
- Invalid or unreachable URL returns an error — ensure the URL is absolute and accessible
- Private or paywalled pages may return incomplete or empty content
- Very large pages may be truncated or slow to process
- Non-HTML responses (e.g. PDFs, binary files) may not extract meaningful content
- Pages requiring JavaScript rendering may return incomplete content if the site relies heavily on client-side rendering
