## 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-web-url-context-distiller-bm25-budget-control-265a3bca
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, keeping it under 2000 tokens and focusing on the query 'payment intent API' using budget mode?

## When to prefer this

Choose this endpoint when you need to read a webpage but want to minimize LLM token consumption and cost. Ideal when passing web content into a context window where space is limited, or when you want BM25-focused extraction to retrieve only the most query-relevant sentences from a long page. Prefer over raw fetch/scrape tools when compression ratio and token budget control matter.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Empty or malformed HTML produces minimal output
- mode=budget without a query or max_tokens may return unfiltered content
- Rate limiting or payment failure (x402) blocks the request
- Very large pages may hit internal processing limits
- URLs behind authentication or 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://sec-intel.agentdiet.dev/v1/context-bloat-eliminator)

## Output

Returns a distilled representation of the webpage in the requested mode (Markdown, structured JSON, skeleton outline, or BM25-focused excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status and billing information.
