How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://defi-yield.agentdiet.dev/v1/paywall-clean-extract)
Output
Returns a 'data' object containing the distilled content in the requested format (markdown, structured JSON, skeleton outline, or BM25-ranked excerpt), plus an roi_proof block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache hit/miss status and billing details.
Example use cases
Reading long docs within context budget
“Pull the content from https://docs.openai.com/guides/function-calling and compress it into budget mode focused on 'how to define tool schemas', keeping it under 600 tokens so it fits in my prompt.”
Structured extraction from a product page
“Fetch https://aws.amazon.com/ec2/pricing/ and give me a structured breakdown of the pricing tables — I want the data as JSON, not a wall of text.”
Skeleton outline of a research article
“Grab https://arxiv.org/abs/2307.09288 and give me just the skeleton outline — section headers and key bullet points — so I can decide if it's worth reading in full.”

Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/paywall-clean-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a web page but must stay within a token budget, or when the raw HTML of a page is too large and noisy for direct LLM consumption. It is particularly valuable when you need BM25-ranked relevance filtering (mode=budget with a query) to extract only the most pertinent paragraphs, or when you want structured JSON tables from a page. Prefer it over generic scrapers when token cost visibility and compression ROI metrics matter to your workflow.
Side effects
- URL is unreachable or returns non-200 — fetch fails with error status
- Paywalled or bot-blocked page returns empty or login-wall content
- max_tokens too small to include any meaningful content
- Invalid mode enum value causes validation error
- Raw HTML input too large exceeds processing limits
- BM25 query provided without mode=budget — query ignored silently
