How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/semantic-html-pruner)
Output
Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, a skeleton outline, or a BM25-ranked budget excerpt depending on mode), plus an 'roi_proof' block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes optional cache status (HIT/MISS) and billing details.
Example use cases
Grounding agent on live documentation
“Grab the content from https://docs.openai.com/api-reference and distill it into structured markdown so I can use it as context — keep it under 3000 tokens.”
Budget-focused excerpt for RAG pipeline
“I need a BM25 excerpt from https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) focused on the query 'attention mechanism', and I need it capped at 500 tokens max.”
Structured data extraction from a news article
“Pull https://techcrunch.com/2025/06/01/openai-funding-round/ and extract it in structured mode so I get the key metadata and tables without all the HTML noise.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/semantic-html-pruner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch and compress a live web page or raw HTML into a token-efficient format before passing it to an LLM — especially when context window cost or size is a concern. The BM25 budget mode is uniquely suited for focused retrieval within a strict token ceiling. Prefer this over generic scrapers when you need both fetching and semantic compression in one step, with built-in ROI metrics showing exactly how many tokens were saved.
Side effects
- Invalid or unreachable URL returns an error status
- mode=budget without a query or max_tokens may return unfiltered or oversized content
- Very large HTML pages may hit processing limits or return partial results
- Paywalled or bot-blocked sites may return incomplete or empty distillation
- max_tokens below 20 is rejected by schema validation
- Raw HTML injection via 'html' field with malformed markup may produce degraded output
