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/spa-markdown-reader)
Output
Returns a JSON object containing the distilled content (Markdown text, structured JSON tables, skeleton outline, or BM25-focused excerpt depending on mode), an ROI proof block showing raw vs distilled token counts, compression ratio, and estimated LLM cost saved, plus optional cache hit/miss status and billing metadata.
Example use cases
Token-efficient docs reader for agents
“Fetch https://docs.openai.com/api-reference and distill it into markdown, keeping it under 800 tokens and focusing on 'embeddings endpoint' — I need it compact enough to fit in my agent's context window.”
Structured product data extraction
“Pull https://www.shopify.com/pricing and extract it in structured mode so I get the pricing tiers and features as clean JSON tables, not a wall of HTML.”
Page skeleton for navigation planning
“Load https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API and give me just the skeleton outline so I can see the section headings without all the content.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read web content but must stay within a token budget, or when raw HTML is too noisy and large for direct LLM consumption. It is especially useful for SPA-rendered pages, documentation sites, and any scenario where compression ratio and cost savings matter. Prefer over generic scrapers when you need BM25-focused relevance filtering or multiple structured output modes (markdown, skeleton, tables).
Side effects
- Invalid or unreachable URL returns an error status
- JavaScript-heavy SPAs may not render fully if fetch times out
- Token budget too low (max_tokens < 20) rejected with validation error
- BM25 query required when mode=budget but missing — returns error
- Raw HTML too large may be truncated or rejected
- Payment failure via x402 protocol blocks the request
