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 hn-pulse-agentdiet-dev-web-url-article-extractor-distiller-3461f3a5
```

Example prompt: Can you pull the main article content from https://example.com/some-long-article and distill it into markdown, keeping it under 500 tokens focused on the topic of AI regulation?

## When to prefer this

Choose this endpoint when an AI agent needs to read web pages efficiently without blowing its context window — especially when you need BM25-focused excerpts around a specific query, need structured extraction of tables/metadata, or want to minimize LLM token costs by compressing raw HTML. Prefer this over generic scrapers when token budget control and ROI reporting matter, or when you need multiple extraction modes (markdown, structured, skeleton, budget) from a single endpoint.

## Known failure modes

- Invalid or unreachable URL returns an error status
- URL behind authentication or paywalls may return incomplete content
- Very large pages may exceed processing limits
- mode=budget without a query parameter may behave unexpectedly
- max_tokens below minimum (20) is rejected
- HTML injection or malformed HTML may produce garbled output
- Rate limiting or payment failure (HTTP 402) if USDC balance is insufficient

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://hn-pulse.agentdiet.dev/v1/article-extractor)

## Output

Returns a 'data' object containing the distilled content in the requested format (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), along with ROI proof metrics showing raw vs. distilled token counts, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
