How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402-audit.agentdiet.dev/v1/paywall-clean-extract)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an 'roi_proof' object showing raw vs distilled token counts, compression ratio percentage, tokens saved, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
Example use cases
Research article compressed for agent
“Pull the content from https://techcrunch.com/2024/05/01/openai-funding-round and distill it into a tight markdown summary — I need it under 500 tokens so it fits in my context window.”
Structured product data from e-commerce page
“Fetch https://www.apple.com/shop/product/MK2E3LL/A and extract it in structured mode so I get all the product details, specs, and pricing as clean JSON tables.”
Topic-focused excerpt from long documentation
“Grab the Stripe docs at builtin://stripe-docs and use BM25 budget mode focused on 'webhook signature verification' — give me at most 300 tokens of the most relevant content.”
Technical details
Endpoint
GEThttps://x402-audit.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 stay within a strict token budget, reduce LLM inference costs, or convert noisy HTML into clean structured data. It is especially valuable for long documentation pages, e-commerce product listings, or any webpage where raw HTML would consume excessive context. Prefer it over generic scrapers when you need BM25-ranked, topic-focused excerpts or when you want quantified proof of token savings (compression ratio, cost saved).
Side effects
- Invalid or unreachable URL returns an error status
- URL behind a hard paywall that blocks fetching returns empty or partial content
- max_tokens set below minimum (20) returns a validation error
- BM25 query provided without mode=budget may be ignored
- Very large pages may exceed processing limits or increase latency
- Rate limits or payment failures via x402 protocol block the request
