How this service works
Pay-per-call tools for AI agents: x402 pre-flight checks (is this endpoint safe to pay?), web pages as clean markdown (with optional JavaScript rendering), Latin American tax-ID validation, npm/PyPI/GitHub lookups, and URL health checks. No API keys, no accounts — pay per request in USDC.
Output
A JSON object containing the page title, format (always 'markdown'), HTTP status code, the full page content as clean markdown text, a boolean indicating whether JavaScript was rendered, a boolean indicating whether the content was truncated, and the word count of the extracted content.
Example use cases
Summarize a news article
“Grab the article at https://www.bbc.com/news/technology-12345678 as clean markdown — I want to summarize it without all the HTML noise.”
Research a competitor's landing page
“Fetch https://stripe.com/pricing as readable markdown so I can analyze their pricing structure.”
Extract documentation for code generation
“Pull the content from https://docs.python.org/3/library/asyncio.html as markdown, up to 150000 characters, so I can use it to help write async Python code.”
Technical details
Endpoint
POSThttps://agents.supremeai.ca/v1/read?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to fetch and read the textual content of any public webpage as clean markdown, especially for AI pipelines that need to process or summarize web content without dealing with raw HTML. It is pay-per-call with no API key required, making it ideal for agentic workflows that need ad-hoc web access on demand.
Side effects
- URL is not publicly accessible — returns non-200 status
- URL points to a binary or non-text resource (PDF, image) — content may be empty or malformed
- JavaScript-heavy SPAs may not render correctly without a rendering flag
- Content exceeds max_chars and gets truncated — check the truncated field in response
- Network timeout for slow-loading pages
- Invalid URL format — request rejected with error
