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/context-trimmer)
Output
Returns a data object containing distilled content in the requested format (Markdown, structured JSON, skeleton, or BM25 excerpt), along with an roi_proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
Example use cases
Token-budget research digest for LLM pipeline
“Fetch https://arxiv.org/abs/2305.10601 and distill it into a BM25 budget excerpt focused on 'transformer attention efficiency', capped at 500 tokens — I need to pass only the relevant bits to my downstream model.”
Competitive pricing page extraction
“Distill https://www.notion.so/pricing into structured JSON tables so I can compare their plan tiers and prices without wading through all the marketing HTML.”
Skeleton outline of long documentation page
“Give me a skeleton outline of https://docs.python.org/3/library/asyncio.html — I just need the section headers and key anchors so I can navigate the page structure programmatically.”

Endpoint
POSThttps://mcp-compiler.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reduce LLM context costs by compressing web pages or raw HTML before passing them to a model, especially when you have a strict token budget or want BM25-ranked relevance filtering. Prefer it over generic scrapers when you need structured output formats (Markdown, JSON tables, skeleton, or budget excerpts) with built-in ROI metrics showing exactly how many tokens and dollars were saved.
Side effects
- URL is unreachable or returns non-200 — fetch failure error
- HTML is malformed and cannot be parsed — extraction returns empty or partial data
- mode=budget used without a query field — BM25 scoring cannot rank passages
- max_tokens set below minimum of 20 — validation error
- URL paywall or bot-block prevents content retrieval — returns empty distillation
- Rate limit or payment failure via x402 — 402 Payment Required response
