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-diet)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), a 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd, plus optional cache hit/miss status and billing details.
Example use cases
Compress docs page for LLM context
“Fetch https://docs.openai.com/api-reference and distill it into Markdown, staying under 1000 tokens total — I want to feed just the essentials to my LLM without blowing the context window.”
BM25 keyword-focused page excerpt
“Distill https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) in budget mode with the query 'attention mechanism self-attention', capped at 500 tokens, so I only get the most relevant sections.”
Extract structure from raw HTML
“I have a raw HTML blob from a product page — can you distill it into a structured JSON format with tables and metadata so I can pull out the pricing and specs without parsing it myself?”

Endpoint
POSThttps://mcp-compiler.agentdiet.dev/v1/context-diet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read or process web content but must minimize token usage before passing it to an LLM. It is especially useful when you have a strict context window budget and want BM25-ranked excerpts focused on a specific query, or when you need structured JSON tables and metadata extracted from arbitrary HTML. Prefer it over generic scrapers when you need built-in compression ROI metrics and multiple distillation modes in a single call.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error status
- HTML payload is empty or malformed — distillation may return minimal or empty data
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget used without a query parameter — BM25 ranking has no focus signal
- Rate limiting or payment failure via x402 — request blocked with 402 response
- Target site blocks crawling (bot protection) — fetch fails or returns CAPTCHA page
