How this service works
Extract the useful content from a public URL as clean Markdown for agents. Uses a browser-backed reader when needed and strips navigation/boilerplate. Exact-match PennyRail gap-arbitrage route.
Output
Returns the main textual content of the requested URL as clean Markdown, with navigation menus, ads, footers, and other boilerplate removed. Uses a browser-backed rendering step when JavaScript execution is needed to load the page content.
Example use cases
Research article summarization
“Pull the content from this academic blog post at https://blog.researcher.io/new-findings-2024 and give me the clean text so I can summarize it.”
Documentation ingestion for agent
“Fetch the page at https://docs.somelib.io/getting-started and extract the actual docs content as markdown so I can feed it into my knowledge base.”
News story extraction
“Get me the readable article text from https://techcrunch.com/2024/05/01/some-story — strip out all the ads and menus, just give me the article in markdown.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/bazaar/web-extractWhen to prefer
Use this endpoint when you need to retrieve and read the human-readable content of a public web page in a clean, agent-friendly markdown format. It is especially useful when the page requires JavaScript rendering (browser-backed) and when boilerplate stripping is important. Prefer it over raw HTTP fetch when you want the article body without navigation, ads, or sidebars.
Side effects
- URL is behind a login wall or paywall — returns empty or partial content
- Page requires complex authentication or CAPTCHA — extraction may fail or return minimal content
- Invalid or unreachable URL — returns error response
- Page has no identifiable main content — may return raw or minimal markdown
- Rate limiting or blocking by target site — request may time out
