# Article Extractor with BM25 Budget Control

> Article Extractor with BM25 Budget Control is a paid API for AI agents from alpha-stream.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches and distills a URL or raw HTML into compact Markdown, structured JSON, skeleton outline, or a BM25-scored token-budget excerpt optimized 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 alpha-stream-agentdiet-dev-article-extractor-with-bm25-budget-control-a4767360 -d '<json body>'
```

Example prompt: Fetch the article at https://techcrunch.com/2024/05/01/openai-news/ and distill it into clean Markdown, staying under 800 tokens and focusing the BM25 budget on 'OpenAI funding round'.

## When to prefer this

Choose this endpoint when you need to reduce token overhead before sending web content to an LLM, especially when working within strict token budgets or trying to minimize LLM API costs. It is particularly valuable for agentic pipelines that crawl multiple URLs and need relevance-ranked excerpts via BM25. Prefer it over generic scrapers when you need structured JSON tables, skeleton outlines, or budget-controlled distillation rather than raw HTML dumps.

## 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 degraded output
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Payment not attached or insufficient — HTTP 402 returned blocking execution
- Idempotency-Key collision — previously cached result returned instead of fresh fetch

## How this service works

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

## Output

Returns a JSON object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), an ROI proof block showing raw vs distilled token counts, compression ratio, and estimated LLM cost saved, plus optional cache hit/miss status and billing details.
