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/url-to-markdown)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt depending on mode), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes optional cache hit/miss status and billing details.
Example use cases
LLM context-aware webpage summarization
“Grab the content from https://openai.com/blog and distill it into markdown budget mode, focused on the query 'GPT-4 updates', and cap it at 1500 tokens so it fits in my prompt.”
Structured data extraction from documentation
“Fetch https://docs.anthropic.com/claude/reference/getting-started-with-the-api and convert it to structured mode so I get the tables and metadata as JSON I can work with programmatically.”
Raw HTML cleanup for ingestion pipeline
“I have some raw HTML from an internal tool — can you distill it to markdown skeleton mode so I just get the outline and headings without all the noise?”

Endpoint
POSThttps://x402broker.com/v1/url-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to ingest web page content into an LLM pipeline with strict token budgets, or when you want BM25-focused relevance filtering to extract only the most query-relevant passages from a page. It is especially useful over generic scrapers when you need built-in token compression metrics and ROI reporting, or when you want multiple distillation modes (markdown, structured, skeleton, budget) in a single API call priced at $0.001 per call.
Side effects
- URL is unreachable or returns non-200 — fetch error with status detail
- Invalid or missing 'url' field — 422 validation error
- max_tokens below minimum of 20 — validation rejection
- BM25 query provided but mode is not 'budget' — may be ignored or error
- Raw HTML too large — potential timeout or truncation
- Paywalled or JS-rendered pages may return incomplete content
- Payment/402 failure if USDC balance insufficient
