# Semantic HTML Pruner — Web URL Distiller

> Semantic HTML Pruner — Web URL Distiller 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 web URL (or accepts raw HTML) and distills it into compact, agent-ready tokens using BM25 budget control and multiple extraction modes

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-semantic-html-pruner-web-url-distiller-0e1d84f4
```

Example prompt: Fetch https://stripe.com/docs/payments/checkout and distill it into clean markdown, keeping it under 800 tokens — I want just the essential content with no nav bars or boilerplate.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost. It is ideal when the source page has heavy HTML boilerplate, navigation, ads, or JavaScript-rendered noise. Use mode=budget with a query and max_tokens when you have a strict context limit. Prefer over generic web scrapers when you need built-in compression metrics (roi_proof) and multiple output formats (markdown, structured, skeleton). Also suitable when passing Stripe or other SaaS documentation to a coding agent via the builtin://stripe-docs shortcut.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- Target page blocks crawlers (robots.txt or Cloudflare) — content may be empty or truncated
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget used without a query parameter — BM25 ranking cannot focus without a query
- Raw HTML provided alongside a URL — behavior may be ambiguous; only one should be used
- Payment not attached — x402 payment required error returned before processing

## 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/semantic-html-pruner)

## Output

Returns a 'data' object containing the distilled output (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an roi_proof object with raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache hit/miss status and billing confirmation.
