## 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 sec-intel-agentdiet-dev-semantic-html-pruner-with-bm25-budget-control-5b74554e -d '<json body>'
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into clean markdown, using budget mode focused on 'payment intents' with a max of 1500 tokens?

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before passing it to an LLM, especially when working with large documentation pages, e-commerce sites, or any URL where raw HTML would exceed context limits. It is particularly valuable when you have a specific topic focus (use budget+BM25 mode) or need structured tables and metadata extracted (use structured mode). Prefer it over generic scrapers when token cost savings and LLM-ready output format are priorities.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- HTML payload is empty or malformed — distillation may produce empty or low-quality output
- BM25 query not provided when mode=budget — may default to unfiltered content
- max_tokens ceiling too low (below 20) — rejected by schema validation
- Rate limiting or payment failure via x402 — billing object absent, request rejected
- Timeout fetching a slow or large URL — partial content or timeout error returned

## How this service works

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

## Output

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