How this service works
Fetch any public URL and return a clean, readable markdown or JSON extract for AI agents. Pass the target as ?url=<encoded>. Ideal when you need to read webpages, docs, or articles without a browser. Blocks script/style tags, normalizes links and images, strips HTML.
Output
A JSON object containing the original URL, the HTTP status code of the fetched page, and the page's main content rendered as clean markdown with headings, paragraphs, and links preserved — HTML boilerplate, ads, and navigation stripped away.
Example use cases
Research article summarization
“Go grab the content from https://arxiv.org/abs/2401.00123 and pull out the clean text so I can summarize it.”
Competitor pricing page monitoring
“Fetch https://www.competitor.com/pricing and extract all the readable text so I can see what plans they currently offer.”
News headline extraction for daily brief
“Pull the clean markdown from https://news.ycombinator.com so I can see what the top stories are right now.”
Technical details
Endpoint
GEThttps://x402-web-extract.senpi-agent.workers.dev/fetch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read and process the text content of any public URL on-the-fly without setting up API keys or managing scraping infrastructure. It is ideal for agentic workflows that need ad-hoc web content access paid via USDC micropayments on Base, especially when the agent already participates in the x402 payment protocol. Prefer it over general-purpose browser automation when you just need clean readable text rather than screenshots or DOM interaction.
Side effects
- Non-200 HTTP status from target URL (e.g. 404, 403, 500) — returned in status field with empty or partial markdown
- Target URL is behind authentication or a paywall — returns 200 but markdown will contain login-wall content rather than article body
- HTTP 402 returned before content if payment not yet made — agent must complete x402 USDC micropayment flow first
- Malformed or missing `url` query parameter — likely returns 4xx error
- JavaScript-rendered single-page apps may return incomplete content if JS is not executed
- Rate limiting or bot-blocking by the target site may result in empty or error markdown
