# URL to Markdown Web Distiller

> URL to Markdown Web Distiller is a paid API for AI agents from mcp-security.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage URL (or accepts raw HTML) and distills it into compact, token-efficient Markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt for AI agents

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mcp-security-agentdiet-dev-url-to-markdown-web-distiller-f4d1ee11
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 500 tokens and focusing on the query 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to read or process web page content while minimizing token consumption and LLM costs. It is especially valuable when working with long documentation pages, news articles, or HTML-heavy sites where raw content would exceed context windows. The BM25 budget mode is ideal when only a topically relevant excerpt is needed. Prefer this over generic HTTP fetch tools when token efficiency, structured output (tables, skeleton), or cost ROI tracking is a priority.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- URL points to a PDF or binary file not parseable as HTML — unstructured content may produce poor distillation
- max_tokens set too low (below 20) — request rejected by schema validation
- BM25 query provided without mode=budget — query parameter ignored silently
- Raw HTML provided via 'html' parameter is malformed — distillation quality may degrade
- Payment not completed via x402 — 402 Payment Required response blocks execution

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/url-to-markdown)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON, skeleton outline, or BM25-focused excerpt depending on mode), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing details.
