# Article Extractor with BM25 Budget Control

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

Fetches a URL or distills raw HTML into clean Markdown, structured JSON, skeleton outline, or a BM25-ranked token-budgeted excerpt for LLM consumption

## 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 token-intel-agentdiet-dev-article-extractor-with-bm25-budget-control-6f540f30 -d '<json body>'
```

Example prompt: Can you distill https://stripe.com/docs/payments/accept-a-payment into clean markdown and keep it under 2000 tokens — use budget mode with a query focused on 'payment integration steps'?

## When to prefer this

Choose this endpoint when you need to preprocess web content for LLM consumption and want to minimize token usage and API costs. It is especially valuable when working with long articles, documentation pages, or HTML payloads that need to be trimmed to a strict token budget using BM25 relevance ranking. Prefer this over generic scrapers when you need ROI metrics (tokens saved, compression ratio) alongside distilled content, or when you need multiple output modes (Markdown, structured, skeleton, budget excerpt) from a single service.

## Known failure modes

- Invalid or unreachable URL returns a fetch error
- max_tokens too low (below 20) causes validation rejection
- query field required but missing when mode=budget
- Raw HTML too large may hit processing limits
- Payment failure via x402 results in 402 response before distillation occurs
- URL behind authentication/paywalls may return incomplete content

## How this service works

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

## Output

Returns a `data` object containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an `roi_proof` block showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes a `cache` block (HIT/MISS) and billing details.
