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/rag-token-diet)
Output
Returns a 'data' object containing the distilled content in the requested format (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' object showing raw vs. distilled token counts, compression ratio percentage, tokens saved, ROI multiplier, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing metadata.
Example use cases
Summarize documentation for RAG pipeline
“Fetch and distill https://docs.openai.com/api into clean markdown so I can load it into my RAG system without blowing my token budget.”
Topic-focused page excerpt for research
“Grab the content from https://en.wikipedia.org/wiki/Large_language_model and give me a BM25 budget excerpt focused on 'training data', capped at 300 tokens.”
Structured product catalog extraction
“Distill https://www.vercel.com/pricing into structured JSON tables so I can compare their plan features and prices in one shot.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/rag-token-diet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to read a webpage but must stay within a token budget, reduce LLM inference costs, or produce clean structured content from messy HTML. It is especially valuable in RAG pipelines where raw webpage tokens are too expensive or noisy. Prefer it over generic scrapers when you need built-in BM25 topic-focusing, multiple distillation modes (markdown/structured/skeleton/budget), and ROI proof of how many tokens were saved.
Side effects
- URL is unreachable or returns non-200 status — fetch fails with error status
- Token budget (max_tokens) too low to produce meaningful content — may return truncated or empty excerpt
- Invalid mode enum value — request rejected with schema validation error
- Raw HTML too large — may timeout or exceed processing limits
- BM25 query missing when mode=budget — defaults may produce unranked output
- Payment not settled via x402 — 402 response blocking content return
