# Semantic HTML Pruner – Web URL to Agent-Ready Tokens

> Semantic HTML Pruner – Web URL to Agent-Ready Tokens is a paid API for AI agents from email-verify.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, token-efficient Markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt for LLM 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 email-verify-agentdiet-dev-semantic-html-pruner-web-url-to-agent-afe602c4
```

Example prompt: Can you fetch the Stripe documentation page at https://stripe.com/docs/payments and distill it into clean Markdown, keeping it under 2000 tokens and focusing on the payment intents section?

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM and want to minimize token usage and cost — especially when the raw HTML is too large for your context window. It is ideal for agentic pipelines that repeatedly scrape or monitor web pages and need reproducible, structured, or token-bounded output. Prefer it over generic scrapers when you need BM25 relevance filtering (budget mode), structured JSON extraction, or explicit compression-ratio proof for cost accounting.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Target site blocks the fetcher (403/bot protection) causing empty or failed extraction
- Malformed HTML input may produce incomplete distillation
- Token budget too low (below 20) is rejected by schema validation
- Rate limiting or payment failure (x402) blocks the request
- Mode=budget without a query or max_tokens may produce undefined behavior

## How this service works

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

## Output

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