How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://preflight.agentdiet.dev/v1/rag-chunk)
Output
Returns a JSON object containing the distilled content (as Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), an ROI proof block showing raw vs distilled token counts, tokens saved, compression ratio percentage, and estimated LLM cost saved, plus optional cache hit/miss status and billing details.
Example use cases
RAG pipeline web grounding
“Fetch and distill https://openai.com/blog/gpt-4o into clean Markdown so I can feed it into my RAG pipeline without blowing my token budget.”
Structured data extraction from docs
“Pull the pricing table from https://www.anthropic.com/pricing and return it as structured JSON so my agent can compare model costs.”
Focused excerpt for research query
“From https://en.wikipedia.org/wiki/Transformer_(machine_learning_model), extract only the sections most relevant to 'attention mechanism' using budget mode and cap it at 300 tokens.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/rag-chunk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed live web content into an LLM or RAG pipeline while aggressively controlling token usage. It is especially valuable when you already have a raw HTML string to process directly, when you need BM25-ranked focused excerpts rather than full-page summaries, or when you want built-in ROI reporting on token savings. Prefer it over generic web scrapers when token budget enforcement and multiple distillation modes (Markdown, structured, skeleton, budget) are needed in a single API call.
Side effects
- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- Raw HTML too large to process within service limits — truncation or error response
- mode=budget used without a query parameter — BM25 ranking may default or fail
- max_tokens set below minimum of 20 — validation error
- Payment not authorized or x402 flow fails — billing error preventing execution
- URL contains paywalled or bot-blocked content — distillation returns empty or partial data
