How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/spa-markdown-reader)
Output
Returns a 'data' object containing the distilled content in the requested format (Markdown string, structured JSON tables/metadata, skeleton heading outline, or BM25-ranked excerpt), along with an roi_proof block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
Example use cases
RAG pipeline page compression
“Distill https://docs.openai.com/api-reference into structured markdown for me — I need it compact enough to fit in my LLM context window, so use budget mode with a max of 3000 tokens and focus the BM25 query on 'chat completions'.”
Competitive pricing page extraction
“Fetch https://www.notion.so/pricing and extract it in structured mode so I get the pricing tiers and plan details as clean JSON tables I can compare.”
Skeleton outline of a long article
“Take https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and give me a skeleton outline of the page structure — just the headings and key sections, nothing more.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compress a live webpage or raw HTML into a token-efficient format for LLM context windows, RAG pipelines, or agent workflows — especially when you want BM25-focused excerpts around a specific query, structured JSON tables from a page, or a skeleton outline. Prefer it over generic scrapers when token budget control and compression metrics (roi_proof) are important, or when you need multiple distillation modes from a single endpoint.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error status
- HTML payload is malformed or too large — distillation may fail or truncate
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget used without a query — BM25 ranking may produce generic output
- Paywalled or JS-rendered pages may not be fully fetched — content may be partial
- Payment/402 not resolved — call fails with HTTP 402 if billing is not configured
