How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402-audit.agentdiet.dev/v1/pdf-extract)
Output
Returns a JSON object containing the distilled content (markdown, structured tables/metadata, skeleton outline, or BM25 excerpt depending on mode), plus ROI proof metrics showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
Example use cases
Documentation page compression for agents
“Grab https://docs.openai.com/api-reference and distill it into structured markdown under 800 tokens so I can include it in my agent's system prompt without blowing the context limit.”
BM25-focused research snippet extraction
“Fetch https://en.wikipedia.org/wiki/Large_language_model and pull out only the parts relevant to 'training data and compute costs' using budget mode with a max of 500 tokens.”
Skeleton outline of a long article
“Take this URL https://www.nytimes.com/2024/01/15/technology/ai-regulation.html and give me just a skeleton outline — headings and key structure — so I can quickly see what topics it covers.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/pdf-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reduce token consumption before passing web content to an LLM — especially when working with long documentation pages, articles, or HTML payloads that would exceed context limits or inflate costs. Prefer it over raw web scraping when you need the output to be immediately LLM-ready (markdown or structured JSON) rather than raw HTML. The BM25 budget mode is especially useful when you have a specific question and want only the most relevant excerpts from a page within a strict token ceiling.
Side effects
- Invalid or unreachable URL returns an error status
- max_tokens below minimum (20) causes validation error
- BM25 query missing when mode=budget may return unfiltered budget result
- Raw HTML too large may cause timeout or partial distillation
- Payment failure via x402 returns HTTP 402 without processing
