How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://hn-pulse.agentdiet.dev/v1/clean-html)
Output
Returns a JSON object with a 'data' field containing distilled content (Markdown, structured tables, skeleton, or BM25-focused excerpt depending on mode), plus ROI proof metrics showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved. Also includes cache hit/miss status and billing details.
Example use cases
Summarize a docs page for an agent
“Fetch the content from https://docs.openai.com/api-reference and distill it into structured markdown so I can pass it to my agent without blowing my context window.”
Budget-capped research extraction
“Grab the article at https://techcrunch.com/2024/05/01/openai-news and extract only the parts relevant to 'funding round', keeping the output under 300 tokens using budget mode.”
Skeleton outline of a landing page
“Pull the page at https://linear.app and give me a skeleton outline of its structure so I can quickly understand how it's organized without reading the whole thing.”

Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/clean-html?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed webpage content to an LLM agent but want to minimize token consumption — especially when working with long documentation pages, articles, or HTML dumps. It is particularly valuable in budget-constrained agentic pipelines where you need BM25-focused relevance filtering within a strict token ceiling. Prefer it over raw fetch+parse approaches when you want built-in compression metrics and multiple output modes (markdown, structured, skeleton, budget).
Side effects
- Invalid or unreachable URL returns an error status
- Raw HTML too large may be truncated or rejected
- max_tokens below minimum (20) triggers validation error
- mode=budget without a query may produce suboptimal BM25 excerpts
- Paywalled or JavaScript-rendered pages may yield incomplete extraction
- HTTP 402 payment required if agent lacks valid x402 payment credentials
