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/html-to-markdown)
Output
Returns a JSON object containing: (1) distilled content under 'data' — Markdown text, structured JSON tables, skeleton outline, or BM25-filtered excerpt depending on mode; (2) 'roi_proof' metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD; (3) optional 'cache' metadata indicating HIT/MISS and latency; (4) optional 'billing' details including agent ID, payment method, and fee charged.
Example use cases
Research page summarized for agent context
“Grab https://openai.com/research/gpt-4 and distill it into clean markdown so I can drop it into my agent's context window without blowing my token budget.”
BM25 budget excerpt for targeted Q&A
“Fetch https://docs.aws.amazon.com/lambda/latest/dg/welcome.html and pull out only the sections most relevant to 'cold start latency', keeping the output under 500 tokens.”
Structured data extraction from a product page
“Convert https://www.bestbuy.com/site/apple-macbook-pro/123456.p into structured JSON tables showing the product specs and pricing details.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/html-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read and process web pages without exhausting its context window — especially when token efficiency matters. It is particularly valuable when you want BM25-focused excerpts to answer a specific question from a long page, or when you need structured JSON tables extracted from HTML rather than raw prose. Prefer this over a generic web scraper when you need built-in token budget enforcement and ROI metrics for LLM cost tracking.
Side effects
- Invalid or unreachable URL returns an error status
- Raw HTML input too large may time out or be rejected
- mode=budget without a query or max_tokens may return unfiltered content
- Paywalled or JavaScript-heavy pages may yield empty or minimal content
- Token budget too low (below 20) returns a validation error
- HTTP 402 payment required if x402 payment not provided
