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-chunk)
Output
Returns a distilled representation of the target URL in the chosen mode (markdown, structured JSON tables/metadata, skeleton outline, or BM25-focused budget excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and cache hit/miss status.
Example use cases
RAG pipeline cost reduction
“Fetch https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and distill it down to at most 300 tokens using budget mode, focused on the query 'attention mechanism', so I can pass it cheaply into my RAG pipeline.”
Structured data extraction from docs page
“Pull the page at https://docs.openai.com/api-reference/chat and extract all structured tables and metadata from it in structured mode so I can parse the fields programmatically.”
Quick skeleton outline of article
“Get me a skeleton outline of https://techcrunch.com/2024/05/01/ai-agents-rise so I can see the main headings and sections without reading the whole thing.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/rag-chunk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pass web content into an LLM context window efficiently and cost-effectively, especially when token budget is a concern. Ideal for RAG pipelines, agent research workflows, or any scenario where you need structured or compressed web content with measurable token savings. Prefer the budget mode with a BM25 query when you want topically focused extraction rather than full-page distillation.
Side effects
- URL unreachable or returns non-200 status — endpoint may return an error status
- URL paywall or bot-blocking — content cannot be fetched
- max_tokens too small to produce meaningful output — may return truncated or minimal content
- Invalid mode enum value — returns validation error
- BM25 query missing when mode=budget — may return unfiltered or error
- Payment failure via x402 — call not processed if USDC payment not completed
