## 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-article-extractor-with-bm25-budget-control-4f81d340 -d '<json body>'
```

Example prompt: Pull the main article content from https://example.com/news/article and distill it using budget mode focused on 'AI regulation' with a max of 500 tokens, so I can read just the relevant parts without wasting tokens.

## When to prefer this

Choose this endpoint when you need to fetch and clean web content for LLM consumption while minimizing token usage — especially with budget mode + BM25 query for topic-focused extraction. Prefer it over generic scrapers when you need ROI proof (tokens saved, cost reduced) or when you want structured JSON output from articles. The built-in token budget ceiling (max_tokens) makes it ideal for cost-constrained agent pipelines.

## Known failure modes

- Invalid or unreachable URL returns a fetch error
- HTML too large or malformed may fail distillation
- mode=budget without a query or max_tokens may produce suboptimal output
- Rate limiting or payment failure ($0.001/call via x402) blocks execution
- Private or paywalled pages may return empty or partial content
- max_tokens set too low may truncate meaning fully

## 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/article-extractor)

## Output

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