# Web URL to Compact Markdown Distiller

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

Fetches and distills any web URL or raw HTML into compact, agent-ready Markdown or structured output with BM25 budget control to minimize token usage

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 serp-extract-agentdiet-dev-web-url-to-compact-markdown-distiller-29e5fc50
```

Example prompt: Can you fetch https://docs.stripe.com/payments and distill it into clean markdown, keeping it under 2000 tokens and focusing on the 'payment intents' topic?

## When to prefer this

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 for direct LLM consumption. It is especially valuable when BM25-focused extraction is needed to surface only the query-relevant portions of a large page, or when structured/skeleton modes are needed to parse tables and outlines. Prefer over generic scrapers when token efficiency and LLM cost savings are a priority.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL blocked by robots.txt or anti-scraping measures may return empty or partial content
- Exceeding max_tokens with very dense pages may truncate important content
- mode=budget without a query parameter may produce suboptimal BM25 results
- Raw HTML input that is malformed may cause parsing errors
- Payment/billing failure via x402 protocol if agent wallet is underfunded

## How this service works

Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://serp-extract.agentdiet.dev/v1/url-to-markdown)

## Output

Returns a JSON object containing the distilled content (Markdown, structured JSON tables/metadata, skeleton outline, or BM25-focused budget excerpt depending on mode), along with ROI proof metrics showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved. Also includes cache status and billing confirmation.
