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/paywall-clean-extract)
Output
Returns a 'data' object containing distilled content in the requested mode (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes optional cache status and billing info.
Example use cases
Token-budgeted research article extraction
“Fetch https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and give me a BM25-focused excerpt about attention mechanisms, keeping it under 500 tokens.”
Structured table extraction from a webpage
“Pull the content from https://coinmarketcap.com/all/views/all/ and return it as structured JSON tables so I can see the token prices and market caps cleanly.”
Skeleton outline of a long documentation page
“Get the skeleton outline of https://docs.anthropic.com/en/docs/overview so I can see the high-level structure without reading the whole page.”

Endpoint
GEThttps://hn-pulse.agentdiet.dev/v1/paywall-clean-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read web content but must conserve LLM context tokens — especially for long documentation pages, articles, or data tables. Ideal when you need BM25-focused topic extraction within a strict token ceiling, or when you want structured JSON tables or skeleton outlines instead of raw HTML. Prefer over generic scraping tools when token efficiency and ROI metrics matter.
Side effects
- Invalid or unreachable URL returns an error status
- Paywalled content may not be fully extractable
- Token budget too small (below 20) returns a validation error
- Raw HTML too large may exceed processing limits
- Unsupported mode enum value returns a schema error
- Network timeout fetching target URL returns a fetch error
