# AgentDiet HTML-to-Markdown Web Distiller

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

Fetches a webpage by URL (or accepts raw HTML) and distills it into compact Markdown, structured JSON, skeleton outline, or BM25-budgeted excerpts for token-efficient agent consumption

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 workflows-agentdiet-dev-agentdiet-html-to-markdown-web-distiller-b1da4671
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 2000 tokens — use budget mode focused on the query 'payment intents'?

## When to prefer this

Choose this endpoint when an AI agent needs to read web content without blowing its context window — especially when token cost matters. It is distinctly useful over raw fetch because it provides compression ratio proof, multiple distillation modes (markdown, structured, skeleton, budget), and BM25 relevance filtering. Prefer it over generic scrapers when you need quantified token savings, structured JSON output from messy HTML, or strict token ceiling enforcement for a specific query focus.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint may return an error status
- Paywalled or JavaScript-heavy pages may yield sparse or empty content
- Token budget too low (min 20) causes truncated or empty results
- Invalid mode enum value causes bad request
- Missing required 'url' parameter returns validation error
- Rate limiting or payment failure via x402 if USDC balance insufficient

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes optional cache status (HIT/MISS) and billing details.
