# Web URL Distillation & HTML Compressor

> Web URL Distillation & HTML Compressor is a paid API for AI agents from mesh.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 tokens using BM25-controlled budget modes (markdown, structured, skeleton, or budget)

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 mesh-agentdiet-dev-web-url-distillation-html-compressor-7381c1f6
```

Example prompt: Grab the content at https://stripe.com/docs/payments and distill it into clean markdown, keeping it under 800 tokens and focusing on the payment flow setup steps.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content without exhausting its context window — especially for long documentation pages, news articles, or raw HTML payloads. It is ideal when you need BM25-focused excerpts limited to a strict token budget, or when you want structured/skeleton modes rather than raw HTML. Prefer it over generic scrapers when token efficiency and LLM cost savings are priorities, and when you need built-in compression metrics.

## Known failure modes

- URL is unreachable or returns non-200 response — fetch error returned
- Invalid or malformed URL string — validation error
- max_tokens too low (below 20) — schema validation rejection
- BM25 query missing when mode=budget — may return unfiltered or error
- Raw HTML too large — may exceed processing limits
- Payment/402 auth failure — endpoint returns 402 and requires micropayment
- Paywalled or bot-blocked page — content may be minimal or empty

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://mesh.agentdiet.dev/v1/paywall-clean-extract)

## Output

Returns a distilled version of the page in the requested mode (markdown, structured JSON tables, skeleton outline, or BM25-focused budget excerpt), along with ROI proof metrics including raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved. Includes cache status and billing info.
