# Webpage Distiller — Compact Agent-Ready Token Extractor

> Webpage Distiller — Compact Agent-Ready Token Extractor 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 and distills any web URL (or raw HTML) into compact, token-efficient markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt for AI agents.

## 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-webpage-distiller-compact-agent-ready-75fdf1cd
```

Example prompt: Distill the content at https://stripe.com/docs/api into compact markdown and tell me how many tokens you saved compared to the raw page.

## When to prefer this

Choose this endpoint when an AI agent needs to consume live web content without exhausting its context window — especially for documentation sites, news articles, or product pages. It is ideal when token cost matters and BM25-budget mode is needed to focus on a specific topic within a large page. Prefer it over generic scraping tools when you need ROI proof of compression or when feeding structured JSON or skeleton outlines to downstream agents.

## Known failure modes

- Invalid or unreachable URL returns a fetch error with status non-ok
- mode=budget used without providing a 'query' parameter may return unfiltered or error response
- max_tokens set below 20 (minimum) rejected with validation error
- Paywalled or JS-heavy pages may return incomplete or empty distillation
- Missing required 'url' parameter returns a 400-level error
- Payment not processed (402) blocks execution if agent lacks x402 credentials

## 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/webpage-distiller)

## Output

Returns a 'data' object containing the distilled content in the requested format (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), along with an 'roi_proof' block showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and an ROI multiplier. Also includes cache status and billing details.
