How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/rag-token-diet)
Output
Returns a JSON object containing distilled web content in the requested format (Markdown, structured JSON, skeleton, or BM25 budget excerpt), plus an ROI proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
Example use cases
RAG pipeline context compression
“Fetch https://openai.com/research/gpt-4 and distill it into structured markdown under 500 tokens — I need to slot it into a RAG prompt without blowing my context window.”
BM25 budget-focused documentation scrape
“Pull the content from https://docs.anthropic.com/claude/reference and return only the sections most relevant to 'tool use and function calling', capped at 300 tokens using budget mode.”
Skeleton outline of a long article
“Give me a skeleton outline of https://www.nytimes.com/2024/01/15/technology/ai-agents-future.html so I can quickly see the structure and key headings without reading the whole thing.”

Endpoint
GEThttps://x402broker.com/v1/rag-token-diet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed web content into an LLM context window efficiently and token count is a concern. It is especially valuable for RAG pipelines, agent workflows that browse documentation, or any scenario where you need to compress arbitrary web pages into structured, clean text with a measurable compression ratio. Prefer it over generic scrapers when you need BM25-focused relevance filtering, multiple distillation modes, or built-in token budget enforcement.
Side effects
- Invalid or unreachable URL returns an error status
- URL blocked by robots.txt or requires authentication — content unavailable
- mode=budget without a query or max_tokens may produce unoptimized output
- Raw HTML too large may exceed processing limits
- Payment failure (402) if x402 payment is not properly configured
