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

Fetches a URL or raw HTML and distills it into compact, agent-ready Markdown, structured JSON, skeleton outline, or BM25-ranked token budget excerpt

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-compiler-agentdiet-dev-url-to-markdown-web-distiller-agentdiet-d2d9c0f1
```

Example prompt: Fetch the Stripe pricing page at https://stripe.com/pricing and distill it into compact markdown, keeping it under 1000 tokens — I want just the key content without all the HTML noise.

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before passing it to an LLM, especially for long documentation pages, articles, or HTML payloads. It is ideal when you need BM25-focused excerpts within a strict token budget, or when you want structured JSON or skeleton outlines rather than raw HTML. Prefer it over generic scrapers when LLM cost savings and compression metrics matter to your workflow.

## Known failure modes

- URL is unreachable or returns non-200 status — fetch failure error
- Invalid or malformed URL provided — validation error
- max_tokens set below minimum of 20 — schema validation error
- mode=budget used without a query parameter — incomplete BM25 configuration
- Requested page blocks bots or requires authentication — empty or partial content returned
- Token budget too small to meaningfully represent the content — truncated or minimal output

## 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-compiler.agentdiet.dev/v1/url-to-markdown)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt), an 'roi_proof' object showing raw vs. distilled token counts, compression ratio, and estimated LLM cost saved, plus optional billing and cache metadata.
