# Web URL to Compact Markdown Distiller

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

Fetches a webpage URL (or raw HTML) and distills it into compact, agent-ready Markdown, structured JSON, a skeleton outline, or a BM25-budget-controlled excerpt with token savings metrics

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 whale-momentum-agentdiet-dev-web-url-to-compact-markdown-distiller-96ae3387
```

Example prompt: Can you fetch the Stripe docs page at https://stripe.com/docs/api and distill it into compact markdown, keeping it under 2000 tokens and focusing the BM25 query on 'payment intents'?

## When to prefer this

Choose this endpoint when an AI agent needs to read or reference web pages or documentation without exhausting its context window — especially for long API docs, research pages, or HTML-heavy sites. The BM25 budget mode is uniquely suited for targeted extraction when you only need content relevant to a specific query. Prefer this over raw HTML fetching whenever token cost and context efficiency matter. The structured and skeleton modes are ideal when you need machine-parseable tables or just a navigation outline rather than full prose.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — distillation fails with an error status
- HTML payload is malformed or empty — returns empty or minimal data object
- max_tokens is set too low (below 20) — rejected by schema validation
- BM25 query yields no matching tokens within budget — returns empty or minimal excerpt
- Rate limiting or payment failure via x402 — call rejected before processing
- Target page is behind authentication or CAPTCHA — fetch fails silently or returns login page content

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/docs-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-ranked excerpt depending on mode), plus ROI proof metrics (raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, llm_cost_saved_usd, roi_multiplier), cache status (HIT/MISS), and billing info including fee charged in USD.
