## 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-compressor-with-bm25-budget-797186d3
```

Example prompt: Can you fetch and compress https://stripe.com/docs/payments into compact markdown using budget mode, focusing on 'payment intents' and keeping it under 500 tokens?

## When to prefer this

Choose this endpoint when an AI agent needs to read web pages but must minimize LLM token usage and cost. It is especially valuable when processing long documentation pages, news articles, or HTML-heavy sites where full content would overflow context windows. The BM25 budget mode is uniquely suited for targeted extraction when you have a specific query focus and a strict token ceiling. Prefer this over generic scraping APIs when token efficiency and cost savings are primary concerns.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Exceeding the max_tokens minimum of 20 may be rejected
- mode=budget without a query parameter may produce unfocused results
- Raw HTML input that is malformed may cause parsing failures
- Network timeouts when fetching slow or large pages
- Payment/x402 authorization failure if wallet has insufficient funds

## 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-compress)

## Output

Returns a distilled representation of the webpage in the requested mode (markdown, structured JSON tables/metadata, skeleton outline, or BM25-focused budget excerpt), along with ROI proof metrics showing raw vs. distilled token counts, compression ratio, tokens saved, LLM cost saved in USD, and billing details including fee charged.
