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/web-scrape)
Output
Returns a 'data' object containing the distilled content in the requested format (Markdown, structured JSON, skeleton outline, or BM25-trimmed excerpt), along with ROI proof metrics (raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD), cache hit/miss status, and billing details.
Example use cases
Token-budget research from live docs
“Grab the content from https://docs.openai.com/api-reference and compress it to under 600 tokens using budget mode, focused on the query 'function calling'.”
Structured data extraction from product page
“Scrape https://www.apple.com/iphone-16/ and pull out structured tables and metadata — I want the specs and pricing in a clean structured format.”
Skeleton outline of a long article
“Fetch https://en.wikipedia.org/wiki/Large_language_model and give me just the skeleton outline so I can see the document structure without reading the whole thing.”

Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/web-scrape?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to bring live web content into an LLM context window with minimal token overhead — especially when you have a strict token budget (use mode=budget with a query and max_tokens), want structured extraction (tables, metadata), or need a quick skeleton outline. It is purpose-built for agent workflows where every token costs money, providing ROI proof on each call. Prefer it over generic scrapers when compression ratio and cost tracking matter.
Side effects
- Invalid or unreachable URL returns an error status
- Paywalled or JavaScript-heavy pages may yield empty or partial content
- max_tokens below 20 is rejected with a validation error
- mode=budget without a query may produce unoptimized output
- Rate limits or payment failures return 402 or relevant HTTP error codes
- HTML-only mode fails if neither URL nor html is supplied
