How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://prompt-guard.agentdiet.dev/v1/article-extractor)
Output
Returns a 'data' object containing the distilled content in the requested format (Markdown, structured JSON, skeleton, or BM25 excerpt), along with an 'roi_proof' block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, llm_cost_saved_usd, and roi_multiplier. Also includes cache status and billing details.
Example use cases
LLM cost-aware research summarization
“Grab the content at https://arxiv.org/abs/2401.12345 and compress it to under 300 tokens using budget mode, focused on the methodology section, so I can include it in my prompt without blowing my token limit.”
Structured data extraction from product page
“Pull the page at https://stripe.com/pricing and extract it in structured mode so I get the pricing tiers and feature tables as clean JSON I can reason over.”
Documentation skeleton for developer onboarding
“Fetch https://docs.github.com/en/actions and give me a skeleton outline of the page so I can understand the high-level structure before diving in.”

Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/article-extractor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to reduce token overhead before passing web content to an LLM — especially when working within a strict token budget or cost constraint. It is ideal for agentic pipelines that routinely fetch and process URLs, where BM25-focused extraction can target only the relevant passage rather than the full page. Prefer it over generic scrapers when you need ROI proof of compression savings or structured/skeleton modes for downstream parsing.
Side effects
- Invalid or unreachable URL returns an error status
- max_tokens below 20 rejected with validation error
- mode=budget without a query may return unfiltered or fallback content
- Paywalled or JavaScript-heavy pages may yield partial or empty extraction
- Rate limiting or payment failure (x402) blocks the request
