How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://domain-osint.agentdiet.dev/v1/spa-markdown-reader)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, a skeleton outline, or a BM25-ranked excerpt), plus an 'roi_proof' block showing raw token count, distilled token count, tokens saved, compression ratio, and estimated LLM cost saved. Also includes optional cache hit/miss status and billing details.
Example use cases
Read competitor pricing page for agent
“Fetch https://openai.com/pricing and distill it into compact markdown so I can see what models and prices they list — keep it concise.”
Budget-capped research on a long article
“Grab https://en.wikipedia.org/wiki/Large_language_model and return only the parts relevant to 'training data and compute', capped at 500 tokens using budget mode.”
Structured extraction of a documentation page
“Distill https://docs.github.com/en/rest into structured mode so I get the key tables and metadata in JSON format rather than raw HTML.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a live web page but must stay within a token budget — especially for long documentation pages, news articles, or SPA-rendered sites. Prefer it over generic web scrapers when you need BM25-focused relevance filtering, structured table extraction, or skeleton outlines rather than raw HTML dumps. Ideal for agentic pipelines where downstream LLM costs matter and compression ROI is important.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error status
- Page is heavily JavaScript-rendered and content cannot be extracted — sparse or empty data returned
- Token budget (max_tokens) set too low to return meaningful content
- BM25 query provided without mode=budget — query parameter may be ignored
- Invalid mode enum value causes a validation error
- Raw HTML passed via 'html' parameter is malformed — distillation may be incomplete
