How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/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), an 'roi_proof' object showing raw tokens, distilled tokens, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD, plus optional cache hit/miss status and billing details.
Example use cases
Documentation extraction for agent context
“Grab https://docs.openai.com/api-reference and distill it into clean markdown so I can use it as context — keep it tight, under 3000 tokens with budget mode and focus on 'rate limits and errors'.”
Competitive webpage summarization
“Pull the content from https://competitor.com/pricing and give me a structured summary of their pricing tiers — use structured mode so I get it as JSON tables.”
Research article distillation
“Take this raw HTML I'm pasting and extract just the main article body as clean markdown, stripping all the nav, ads, and footer junk.”

Endpoint
POSThttps://x402broker.com/v1/paywall-clean-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch and clean a webpage or process raw HTML into a compact, LLM-friendly format with measurable token savings. It is especially valuable when you have a specific topic query and need BM25-ranked budget excerpts to stay within a strict token limit, or when you need structured JSON tables extracted from a page. Prefer it over generic scrapers when ROI proof and token compression metrics matter to your pipeline.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error status
- HTML payload is empty or malformed — distillation may return minimal or empty data
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Paywalled or JavaScript-rendered pages may not be fully fetched
- Payment failure via x402 protocol results in 402 response before execution
