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/pdf-extract)
Output
Returns a data object containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), a cache status object with HIT/MISS and latency, billing details, and an roi_proof block showing raw vs distilled token counts, compression ratio percentage, tokens saved, ROI multiplier, and estimated LLM cost saved in USD.
Example use cases
Compress documentation page for agent
“Grab the OpenAI API reference at https://platform.openai.com/docs/api-reference and distill it into clean markdown — I need it under 1500 tokens, so use budget mode with the query 'authentication and rate limits'.”
Extract structured data from a pricing page
“Pull https://vercel.com/pricing and distill it into structured mode so I get the pricing tiers and feature comparisons as JSON tables, not a wall of HTML.”
Outline a long blog post before reading
“Fetch this article at https://martinfowler.com/articles/microservices.html and give me just the skeleton outline so I can see the section headers before deciding which parts to read in full.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/pdf-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read or process web pages but must stay within a token budget or minimize LLM costs. It is especially valuable over raw fetch/scrape tools when you need clean, structured, or summarized output rather than raw HTML, and when token efficiency is a primary concern. The BM25 budget mode is uniquely useful when only a relevant slice of a large page is needed. Prefer it over generic web scrapers when you want built-in compression metrics and cost-savings proofs.
Side effects
- URL is unreachable or returns non-200 — fetch error returned
- URL is valid but page requires JavaScript rendering — may return incomplete or empty content
- max_tokens set too low (below 20) — schema validation error
- mode=budget used without a query parameter — BM25 scoring has no focus signal
- Raw HTML provided but is malformed or empty — distillation may return minimal output
- Payment not provided for x402-gated endpoint — 402 Payment Required response
