How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://serp-extract.agentdiet.dev/v1/html-to-markdown)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured tables/metadata, skeleton outline, or BM25-filtered 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
Summarize competitor pricing page
“Grab https://www.competitor.com/pricing and distill it into clean markdown — I want to see their pricing tiers without all the HTML noise, keep it under 800 tokens focused on the query 'pricing plans'.”
Extract article body from news URL
“Take this news article URL https://techcrunch.com/2024/05/01/some-article and convert it to clean markdown so I can read just the article text without ads or navigation clutter.”
Condense raw HTML for LLM context
“I have a raw HTML blob from a scraped page — can you distill it into structured markdown tables and metadata so it fits in my LLM context window? Use structured mode.”

Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/html-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert a live URL or raw HTML into compact, LLM-ready Markdown and want fine-grained control over token budgets. It is especially valuable when you want BM25 query-focused filtering to extract only the most relevant passage from a noisy webpage, keeping LLM context costs low. Prefer it over generic scrapers when you need compression ratios, ROI proof, and structured output modes (skeleton, tables, budget) in a single call.
Side effects
- URL unreachable or returns non-200 — distillation cannot proceed
- HTML too malformed to parse — may return empty or partial markdown
- Token budget too low (below 20) — rejected by schema validation
- BM25 query returns no relevant matches — budget excerpt may be empty
- Rate limiting or payment failure via x402 — request blocked
- Very large pages may hit processing limits or return truncated output
